Question

10. Use data from your textbook’s appendix to determine ΔG° for the following reaction at 549 K and standard conditions:
CH2O(g) + 2 H2(g) ⇌ CH4(g) + H2O(g).
(a) 193.7 kJ

(b) ‒193.7 kJ

(c) 5.749×104 kJ

(d) ‒150.1 kJ

11. Determine the equilibrium constant (K) for the reaction in the problem above. CH2O(g) + 2 H2(g) ⇌ CH4(g) + H2O(g).
(a) 481

(b) 1.07×109

(c) 2.08×10‒3

(d) 1.87×1014

 

                     CH2O(g) + 2 H2(g) ⇌ CH4(g) + H2O(g).

H(kJ/mol)       -108.6        0             -74.6         -241.8

S (J.mol k)       218.8         130.7       186.3          188.8
