Critique of Hinshelwoods theory

Answer. The theoretical equations are in molecular units. Both Z and EA are given in molar units. But note (—EA/RT) = (so/kT), and in this case EA, given in kJ mol-1, does not have to be converted to a molecular quantity. 

From these values it is clear that allowing accumulation of energy into more than one vibrational mode dramatically increases the rate of activation. A value of 5 = 6 corresponds to a non-linear molecule with four atoms. If larger molecules were considered, s would be much larger and the increase in kx even more dramatic.
