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 0.18 bar of N2, 0.36 bar of H2 and 0.58 bar of NH3, describe the situation:



1. Q > K and more products will be made to reach equilibrium.

2. Q > K and more reactants will be made to reach equilibrium.

3. Within 1 decimal place, Q = K and the reaction is at equilibrium

4. Q < K and more products will be made to reach equilibrium.

5. Q < K and more reactants will be made to reach equilibrium.
