The concept of higher-order frequency response functions(FRFs), which is based on Volterra series representation of nonlinear systems, is used to analyse the time-average performance of a perfectly mixed reactor subject to periodic modulation of the inlet concentration, for a simple n-th order heterogeneous catalytic reaction. The second order frequency response function G2(o, o), which corresponds to the dominant term of the non-periodic(DC) component, essentially determines the
average performance of the periodic process.Thus, in order to evaluate the potential of a periodic
operation, it is sufficient to derive and analyse the G2(o, o) function. The sign of this function defines
the sign of the DC component and reveals whether the periodic operation is favourable compared to
conventional steady state operation,or not. It will be shown that, for the case investigated,the sign of
this function depends both on the reaction order and on the shape of the adsorption isotherm
