1.

Which increases on increase of temperature

Answer»

Energy of ACTIVATION ` (E_(a))`
Collision frequency (Z)
Rate constant (k)
Both (B) and ( c)

Solution :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 .
