Question

The graph below shows an energy diagram for three chemical reactions.  Pick your favorite one and indicate:

  • the activation energy
  • the transition state
  • the free energy change for that reaction

Draw a new curve on the graph to indicate how an enzyme that catalyzes the reaction will change the energetics.

This image shows a reaction coordinate diagram, which illustrates the energy changes during a chemical reaction. The x-axis is labeled "RXN Coordinate" and the y-axis is labeled "E," representing energy.

- Point A represents the reactants' energy level.
- From A to B, the energy decreases slightly, indicating an initial step in the reaction.
- Point B is a local minimum, signifying an intermediate state with lower energy.
- The energy then rises significantly to a peak, a transition state, before reaching point C.
- Point C is another intermediate with lower energy than the peak but higher than B.
- Finally, the energy decreases to point D, which represents the products' energy level and is lower than the initial reactants' level at A.

This diagram is used to understand the steps and energy changes involved during the reaction process and helps in identifying transition states and intermediates.
