Consider the Arrhenius equation given below and mark the correct option.
k = A e–Ea /RT
The given Arrhenius equation can be written as
Here, A is the Arrhenius constant, Ea 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 Ea decrease and T increases with the passage of time.
As shown in equation 1 and equation 2.
Thus option (iv) is correct.
