Physical Chemistry Help Please!

In the Haber process, ammonia is produced by passing a mixture of nitrogen and hydrogen over a catalyst:
N2(g) + 3H2(g) → 2NH3(g)
a) Calculate ∆rH*, ∆rS*, ∆rG*, and K for the reaction at 298 K.
b) An industrial reactor operates at 600 K. Calculate K at this temperature, assuming heat capacities to be independent of temperature.
c) The gas flowing into the reactor has the composition ratio 3 mol H2: 1 mol N2. If the mole fraction of ammonia in the exhaust gas from the reactor is 0.35, what is the total pressure in the reactor? (Assume that equilibrium is established in the reactor at 600 K).

I've done parts a and b using data from the question but no idea how to do part c?
