Question
Consider the gas-phase reaction, N2(g) + 3 H2(g) <=> 2 NH3 (g), for which Kp = 43 at 400 K. If the mixture is analyzed and found to contain 0.3 bar of N2, 0.5 bar of H2 and 1.3 bar of NH3, describe the situation:
a) Q < K and more products will be made to reach equilibrium.
b) Within 1 decimal place, Q = K and the reaction is at equilibrium
c) Q > K and more reactants will be made to reach equilibrium.
d) Q > K and more products will be made to reach equilibrium.
e) Q < K and more reactants will be made to reach equilibrium.
Explanation / Answer
Q= (1.3)^2/(0.3)*(0.5)^3 = 45.06
so Q> K and moreproducts will be made to reach equilibrium
