Maybe you try to integrate the mass balance equation directly with the assumed form of the kinetic equation and of course with the known, linearly changing temperature. Numerically, it's not difficult. The R-K IV integration method is quite sufficient. However, if you conduct kinetic studies of a complex process under non-isothermal conditions, parameter E can only be interpreted as a measure of process sensitivity to temperature change, not as activition energy.
