Which increases on increase of temperature

Options

A. Energy of activation ` (E_(a))`
B. Collision frequency (Z)
C. Rate constant (k)
D. Both (b) and ( c)

Answer

d

Explanation

The collisions frequency (Z) and rate constant (k) increase on increase of temperature . With the increase in temperature , the average kinetic energy of the molecules increases and this leads to an increase in number of collisions per unit time (Z). The rate constant (k) of a reaction is also increases with increase of temperature .
