B

An exponential increase in rate constant

C

Both (a) and (b)

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C
On increasing the temperature or decreasing the activation energy, rate of reaction increases and an exponential incerease ini rate constant also occurs.

What will happen if temperature is increased in the dissolution of CO_(2) gas in water ?

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. The pre-exponetial factor in the Arrhenius equation of a first order reaction has the unit :
