1. Can't you look up values of delta Go at 25C, find delta Go for the rxn;
delta Go rxn = (sum delta Go product)-(sum delta Go reactants).
Tben delta Go = -RTlnK
Use delta Go to calculate K and from there
Kp = PCO2

3. Ally did you convert the kJ you would have most likely calculated for your change G0rxn to J to make the R constant work properly?
