Definition of heat capacity of activation, Cpo (SI unit: J mol-1 K-1)

A quantity related to the temperature coefficient of H (enthalpy of activation) and S (entropy of activation) according to the equations:

Cp = (H/T)p = T(S/T)p

If the rate constant is expressible in the form ln k = a/T + b + c ln T + dT, then

Cp = (c - 1) R + 2dRT

See KOHNSTAM (1967).
