The overall rate constant of a reaction is such as:
\(k_r=\frac{k_a.k_b}{k'_a}\)
where ka, k'a and kb are rate constant of activation, deactivation and decomposition step. Provided that the sum of activation energy of activation and decomposition step is smaller than activation energy of deactivation step. On increasing the temperature,
1
The rate of reaction will increase
2
The rate of reaction will decrease
3
The rate of reaction will first increase than decrease
4
The rate of reaction will remain constant
