In the Arrhenius equation: k = A exp(-E(...

In the Arrhenius equation: `k = A exp(-E_(a)//RT)`, the rate constant

A

Decreases with increaisng activation energy and increases with temperature.

B

Increases with activation energy and temperature.

C

Decreases with activation energy and temperature.

D

Increases with activation energy and decreaisng temperature.

Text Solution

Verified by Experts

The correct Answer is:
D
It `T` is high, if `E_(a)` is high, `k` is low.
It `T` is low, `k` is low, if `E_(a)` is low, `k` is high.
