Which step is faster, (a) C to D or (b) C to B?

Use the reaction energy diagram above to answer the following questions

Calculate the activation energy, ?G, for the step C to D.  kcal/mol

Calculate the overall energy change, ?G°, for the process A to B.  kcal/mol

Which step is faster, (a) C to D or (b) C to B?

Explanation / Answer

Question 1

the activation energy, G, for the step C to D : 4 kcal/mol

the overall energy change, G°, for the process A to B: 5 kcal/mol

(a) C to D step is faster because it needs only 4 kcal/mol for activatio while  C to B needs 15 kal /mol

Question 2

the activation energy, G, for the step C to D. 4 kcal/mol

the overall energy change, G°, for the process A to B. 11 kcal/mol

(a) C to D step is faster because it needs only 4 kcal/mol for activatio while  C to B needs 17 kal /mol
