Q. The potential energy diagrams for four reactions are given below Which one of the following statements about these diagrams is incorrect?
KEAM
KEAM 2006
Chemical Kinetics
A
I has the largest rate constant for an exothermic reaction.
0%
B
II has the smallest rate constant for the reverse reaction.
8%
C
III will have the most rapid establishment of equilibrium.
19%
D
IV has the largest rate constant for an endothermic reaction.
62%
E
The magnitude of the enthalpy of reaction I is greater than that of III.
62%
Solution:
From the potential energy diagrams, the statement (d) is not correct, i.e., diagram (IV) has not the largest rate constant for an endothermic reaction.
