12. An equilibrium)mixture at 727 °C contains 0.276 mole of H2 gas, 0.276 mole of CO2 gas, 0.244 mole of CO gas and 0.244 mole of H₂O vapor. CO2(g) + H2(g) → CO(g) + H₂O(g) So, the deltaG° at 727 °C and the direction of the reaction will be: a) - 3.46 KJ/mole and the reaction proceeds in the forward direction b) + 4.36 KJ/mole and the reaction proceeds in the forward direction c) +3.46 KJ/mole and the reaction proceeds in the backward direction d) - 4.36 KJ/mole and the reaction proceeds in the backward direction​
