Answer :

The given Arrhenius equation can be written as

Here, A is the Arrhenius constant, E_{a} is the activation energy, R is Universal gas constant and T is temperature.

If we differentiate both sides with respect to time (t) we get,

……… Equation1

Differentiation of A and R with respect to time t is zero as they are constant values.

As we know,

……. Equation2

Rate constant increases exponentially with time when E_{a} decrease and T increases with the passage of time.

As shown in equation 1 and equation 2.

Thus option (iv) is correct.
