Dear All,

How to calculate the heat of absorption by use of the following form of the Gibbs-Helmholtz equation:

∆Hs/R = [∂ lnp /∂ (1/T)]x

where: x - mole fraction of CO2 in the liquid phase
p - CO2 partial pressure (kPa)
T - temperature (K)
R - universal gas constant
α - mole ratio in the liquid phase (mole CO2 per mole of amine)
