The balanced reaction CO + 2H2 <--> CH3OH is in equilibrium. The equilibrium constant as a function of T is:

K(T) = (yM / yCyH2), where yM = mole fraction of methanol, yC = mole fraction of CO, and yH = mole fraction of hydrogen gas.

100 mol CO and 300 mol H2 are fed into a reactor and allowed to come to equilibrium at 4000C. If at this temperature only 25 mol CO remain in the reactor, what is the equilibrium constant?

Hint: first calculate the number of moles of each component at equilibrium, then use this information to calculate each y, then K.
