Consider the relative energy diagrams for four different pro

Consider the relative energy diagrams for four different processes: A. Free Free Free energy Free energy Reaction Reaction coordinate Reaction coordinate Reaction coordinate Compare energy diagrams A and D. Assuming all other factors (such as concentrations and temperature) are identical for the two processes, identify which process will occur more rapidly. C C C c Process A will occur more rapidly. Process A will occur as rapidly as process D. Process D will occur more rapidly. Both processes are thermodynamically unfavorable. Compare energy diagrams A and B. Which process will more greatly favor products at equilibrium? c c C c Process A will favor products at equilibrium as greatly as process B. Both processes are thermodynamically unfavorable. Process B will more greatly favor products at equilibrium than process A. Process A will more greatly favor products at equilibrium than process B.

Solution

1. Process D will occur more rapidly than process A as the activation energy for process D is slightly lower than A.

2. Process A will favor product more greatly than B.

3. None of the processes exhibit an intermediate but all the processes pass through a transition state.

4. In process C.

5. Process A will occur more rapidly as the activation energy is lower than B.

6. Process D will favor product more greatly than B.

7. In process D.
