Using data from the thermodynamic quantites at 29815 k

Question

Using data from the thermodynamic quantites at 298.15 K, calculate delta H^degree, delta S^degree, and delta G^degree at 298K for each reaction. Show that delta G^degree = delta H^degree - T(deltaS^degree)

(A) H2(g) + F2(g) ->2HF(g)

(B) C(s,graphite) + 2Cl2(g) -> CCL4(g)

(C) 2PCl3(g) + O2(g) -> 2POCl3(g)

(D) 2CH3OH(g) + H2(g) -> C2H6(g) + 2H2O(g)
