Question

The rate constant is given by the equation $K=PZ{e}^{-E/RT}$. Which factor should register a decrease for the reaction to proceed more rapidly?

• A. T
• B. Z
• C. E
• D. P

Answer 1

Answer: (C)

E

Since, $K=PZ{e}^{-E/RT}$

$K\uparrow$ if $P,Z,T,$ is increases and $E$ decreases.

So, by decreasing $E$, $K$ can be increased.
