Before revision: ΔGmix ( Gibbs free energy of mixing ) is defined as: ΔGmix = ΔHmix - TΔSmix where Hmix is defined as enthalpy of mixing, T is temperature, and Smix is entropy of mixing respectively.
After revision: , the Gibbs free energy of mixing , is defined as: ΔGmix = ΔHmix - TΔSmix where is defined as enthalpy of mixing, is temperature, and is entropy of mixing respectively.
