Question

H₂ (g) + Cl₂ (g) -------> 2 HCl (g)
Appendix 4: H2 (g): ∆H^o = 0, ∆S^o = 131 J/K * mol, ∆G^o = 0. Cl2 (g): ∆H^o = 0, ∆S^o = 223 J/K * mol, ∆G^o = 0. HCl (g): ∆H^o = -92 Kj/mol, ∆S^o = 187 J/K * mol, ∆G^o = -95 Kj/mol

a) Calculate ∆H^o, ∆S^o, ∆G^o and equilibrium constant K (at 298 K) using data in Appendix 4 of Zumdahl textbook

b) If H₂ (g), Cl₂ (g), and HCl (g) are placed in a flask such that the pressure of each gas is 1 atm, in which direction will the system will shift to reach equilibrium at 25^oC?

Explain please.
Thanks!
