Question

Compare the reaction energy diagrams for the three gas phase reactions shown below

Assume that steric factors are all comparable and that entropy is not important in the following. Specify a reaction with its number (1,2, or 3).

The reaction with the largest rate constant is

The reaction with largest equilibrium constant is

The reaction whose equilibrium constant increases the most with an increase in temperature is

The strongest bond is the ---Select--- A-A, A-B, A-C, A-D bond.

The weakest bond is the ---Select--- A-A, A-B, A-C, A-D bond.

1) A2 + B AB + A 2) A2 + C AC + A 3) A2 + D AD + A

largest rate constant = 1 as it has lowest activation energy

largest equilibrium constant = 2

3 as it is endothermic reaction

strongest bond = A-C

weakest bond= A-D
