heat capacity of activation, ΔCp

https://doi.org/10.1351/goldbook.H02754
A quantity related to the temperature
coefficient
of ΔH (
enthalpy of activation
) and ΔS (
entropy of activation
) according to the equations: ΔCp=(ΔHT)p=T (ΔST)p If the
rate constant
is expressible in the form lnk=aT+b+c lnT+dT, then: ΔCp=(c1) R+2 d(R T) SI unit: Jmol1K1.
