What does the energy diagram represent?
Energy diagrams are used to represent the change in energy for the molecules involved in a chemical reaction. The free energy is measured along the y-axis, and the reaction coordinate is plotted on the x-axis. The reaction coordinate indicates the progress of the conversion of reactants to products.
What is potential energy diagram in physics?
An energy diagram shows how the potential energy of an object depends on position and tells you all kinds of things about the motion of the object.\nHere's an example energy diagram for the boulder:\n\nThe potential energy curve shows how much potential energy the boulder has at each position.
What indicates potential energy?
potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
What part of a potential energy diagram reveals the enthalpy of reaction?
What part of a potential energy diagram reveals the enthalpy of reaction? The difference in potential energy between the reactants and products.
What other information can be obtained from analyzing a potential energy graph?
Interpreting a one-dimensional potential energy diagram allows you to obtain qualitative, and some quantitative, information about the motion of a particle. At a turning point, the potential energy equals the mechanical energy and the kinetic energy is zero, indicating that the direction of the velocity reverses there.
What is the slope of a potential energy graph?
The negative of the slope of the potential energy curve, for a particle, equals the one-dimensional component of the conservative force on the particle. At an equilibrium point, the slope is zero and is a stable (unstable) equilibrium for a potential energy minimum (maximum).
How does potential energy relate to work?
Energy is the ability to do work, which is when a force is applied to an object and it moves. Potential energy is essentially stored energy that has the ability to do work because of the position or state of the object in question.

Which line represents the total energy?
horizontal lineThe total energy (potential + kinetic) is often represented by a horizontal line added either to the kinetic or potential energy diagrams.

What is the potential energy of a turning point?
At a turning point, the potential energy equals the mechanical energy and the kinetic energy is zero, indicating that the direction of the velocity reverses there.
What is the negative of the potential energy curve?
The negative of the slope of the potential energy curve, for a particle, equals the one-dimensional component of the conservative force on the particle. At an equilibrium point, the slope is zero and is a stable (unstable) equilibrium for a potential energy minimum (maximum).
What is the conservation of mechanical energy?
The conservation of mechanical energy and the relations between kinetic energy and speed, and potential energy and force, enable you to deduce much information about the qualitative behavior of the motion of a particle, as well as some quantitative information, from a graph of its potential energy.
How to find dynamical behavior of mechanical system?
Often, you can get a good deal of useful information about the dynamical behavior of a mechanical system just by interpreting a graph of its potential energy as a function of position, called a potential energy diagram. This is most easily accomplished for a one-dimensional system, whose potential energy can be plotted in one two-dimensional ...
Can kinetic energy be negative?
Since kinetic energy can never be negative, there is a maximum potential energy and a maximum height, which an object with the given total energy cannot exceed: If we use the gravitational potential energy reference point of zero at y0, y 0, we can rewrite the gravitational potential energy U as mgy.
What is potential energy diagram?
Potential energy diagrams. Chemical reactions involve a change in energy, usually a loss or gain of heat energy. The heat stored by a substance is called its enthalpy (H). (Delta H) is the overall enthalpy change for a reaction. Potential energy diagrams can be used to calculate both the enthalpy change and the activation energy for a reaction.
What is a catalyst?
A catalyst provides an alternative reaction pathway which involves less energy and so the catalyst lowers the activation energy. The use of a catalyst does not affect the reactants or products, so (Delta H) stays the same. previous. 1. 2.
Why do products have less energy than reactants?
The products must have less energy than the reactants because energy has been released. This can be shown by a potential energy diagram: EA is the activation energy (energy required to start the reaction) (Delta H) is the quantity of energy given out (ie the enthalpy change) For exothermic reactions, (Delta H) will always be negative.
What happens to the energy between the atoms at R o?
This results in the curve rising as r decreases further. At r o, the energy between the atoms is the lowest. This is point of greatest stability for the molecule.
What is activation energy?
The activation energy represents the amount of energy input to break up the O 2 and H 2 moleculoes. When the atoms combine, there will be a release of energy, much larger than what was put in initially. Oftern, this release of energy provides for the activation energy for further reaction.
Why do atoms need activation energy?
The atoms require some additional energy, known as activation energy, to be injected into the system in order to overcome the potential barrier between them. Only then will bonds start to form. Note: The activation energy often reflects a need to break other bonds, before the one under discussion can be made.

- The point of greatest stability is ro, which gives the equilibrium spacing of the atoms. However, as the atoms approach each other from a large distance, the force is initially repulsive rather than attractive.
