For a certain reaction ?Gorxn = 27.9 kJ/mol. What is the equilibrium constant at 225oC? Remember to convert kJ to J to have consistent units and the temperature to K.
The equilibrium constant, Kp , for the reaction CO(g) + H2O(g)-> CO2(g) + H2(g) at 986°C is 0.63. A rigid cylinder at that temperature contains 1.2 atm of carbon monoxide, 0.20 atm of water vapor
