How do I calculate the Gibbs free energy change for a reaction when given the entropy change, enthalpy change and the reaction conditions>

deltaG= Gibbs free energy deltaG=deltaH - TdeltaS If deltaH= 150 kJ/mol and deltaS=2.1 J/mol we must first convert the deltaS into kJ/mol, this is done by multiplying by 10 -3 . So deltaS= 2.1 x 10 -3 kJ/mol...
