The equilibrium constant for the synthesis of ammonia N2(g) + 3 H2(g) 2 2 NH3(g) has the value K = 6.78 × 10´ at 25°C. Calculate the equi- librium partial pressures of N2(g), H2(g), and NH;(g) at 25°C if the total pressure is 1.00 atm and the H:N atom ratio in the system is 3:1. (Hint: Try the approximation that PN, and PH2 < PNH; and see if the resulting equations are simplified.)
