PLZZ SOLVE THIS

Determine the standard enthalpy change and std. Gibbs free energy change of
reaction at 400 k for the reaction
CO(g) +2H2(g) → CH3OH (g)
At 298.15 K, AH.co (9)= -26.41 kcal/mol, AH CH3OH9)= -48.08 kcal/mol,
AG.co (9)= -32.8079 kcal/mol, AG.CH,0H(9)= -38.69 kcal/mol,
The standard heat capacity of various components is given by,
C9 = a + bT + cT² + dT³, where Co is in cal/mol-K and T is in K
