The reaction: A + 3 B = D + F was studied and the following mechanism was finally determined
A + B = C (fast)
C + B = D + E (slow)
E + B = F (very fast)
The step with largest activation energy is
a. the first step
b. the second step
c. the third step
d. none of the steps has an activation energy
e. all of the steps have the same activation energy
The one with the largest activation energy will be the slowest because it takes more energy to get over the hump.
