For the decomposition of hydrogen peroxide, shown below, the free energy change at 25oC is - 28 kcal/mole. The activation energy is 18 kcal/mole.  H2O2 (l)    ⟶     2 H2O (l)  +  O2 (g)                Δ G = - 28 kcal/mole Draw the free energy diagram for the reaction. In addition to labels for the diagram, label the activation energy and the free energy change.  The diagram does not need to be precisely proportional, estimates are fine. On the free energy diagram, show how the diagram would change if a catalyst were used (using a dashed line, -----). Is this reaction exergonic or endergonic?  Briefly explain.

Question

2.  For the decomposition of hydrogen peroxide, shown below, the free energy change at 25oC is - 28 kcal/mole. The activation energy is 18 kcal/mole. 

H2O2 (l)    ⟶     2 H2O (l)  +  O2 (g)                Δ G = - 28 kcal/mole

  1. Draw the free energy diagram for the reaction. In addition to labels for the diagram, label the activation energy and the free energy change.  The diagram does not need to be precisely proportional, estimates are fine.
  2. On the free energy diagram, show how the diagram would change if a catalyst were used (using a dashed line, -----).
  3. Is this reaction exergonic or endergonic?  Briefly explain.
