At 298K, Go = -67.4 kJ for the reaction

CO + Cl2 --> CoCl2

Calculate the change in Gibbs free energy (in kJ) at the same temperature when P (CO) = 0.368 bar, P (Cl2) = 0.62 bar and P (COCl2) = 0.872 bar. (R = 8.314 J/K mol)

Yes.

Try this but check my thinking. Let me know how this turns out.
delta G = delta Go + RT ln Q.
I would change bars to atmospheres and use Q = PCOCl2/PCO*PCl2
