摘要
The non-steady-state concentration for an EC2 reaction at planar electrode is derived. The asymptotic expression for the non-steady-state current for EC2 reaction is also derived. This paper presents an approximate analytical method (He's homotopy perturbation method) to solve the linear differential equations that describe the diffusion coupled with a reaction rate and time. Approximate analytical expressions for concentration and corresponding current response have been derived for EC2 reaction for small and large value of time and for all values of parameters K (1), k (f) , k (b) using perturbation method.
