Suppose that in an industrial process, N2 at 1.00 bar is mixed with H2 at 3.00 bar, for a total pressure of 4.00 bar, and the two gases are allowed to come to equilibrium with the product ammonia in a reactor of constant volume (in the presence of a catalyst, so the reaction proceeds quickly). At the temperature of the reaction , it has been determined experimentally that K = 977 for reaction R2. What are the equilibrium partial pressures of the three gases?
A mixture consiting of 1.000 mol H2O(g) and 1.000 mol CO(g) is placed ina reaction vessel of volume 10.00 L at 800. K. At equilibrium, 0.665 mol CO2(g) is present as a result of the reaction CO (g) + H2O (g)⇋ CO2(g)+H2(g). What are the value of KC at 800. K?

Hey, The issue I am having here is calculating the partial pressure, if I use P=(n/V)*R*T then I get the partial pressure of H2 as 23.2 but according to the teacher it should be 11.585 so instead of just calculating the the total moles of H2 in the reaction should n be a molar fraction?
