Question

Suppose that nitrogen gas and hydrogen gas are mixed in a container of constant volume at 700 K and in the presence of a catalyst such that the initial partial pressures of nitrogen gas is 2.0 atm and the initial partial pressure of hydrogen gas is 6.0 atm. Under these conditions equilibrium between the reactants and the product ammonia is established. The equilibrium constant, K_P, for this reaction at 700 K is 1.0 x 10^-4. Compute partial pressures of the three gases when equilibrium is established
