Determine Delta G rxn for the process shown: 2 CO(g) + 2 NO(g) <==> 2 CO2(g) + N

Question

Determine Delta G rxn for the process shown: 2 CO(g) + 2 NO(g) <==> 2 CO2(g) + N2(g)

I know that Delta= DeltaH-TdeltaS. I don't know how to approach this problem. Since temperature is not given, do we assume that T=25 C? Then once Delta G is calculated individually, are the values multiplied by the corresponding coefficients, and then solve by Delta G = G final - G initial?

Explanation / Answer

Once the Delta G is calculated individually, Delta G (total) = 2 x delta G(CO2) + delta G(N2) - 2 x delta G(CO) - 2 x delta G(NO)
