The following reaction reaches equilibrium at a temperature of 327 °C. N2(g) + 3 H2(g) <=> 2 NH3(g) ΔH < 0. Which graph (A, B or C) represents percentage yield values obtained at the HIGHEST pressure?

6.1.1
The double arrow "$\rightleftharpoons$" means that the reaction is reversible, indicating that it can proceed in both the forward and reverse directions simultaneously.

6.1.2
Before equilibrium is reached for the first time, the rate of the forward reaction is HIGHER THAN the rate of the reverse reaction.

6.1.3
At equilibrium, the rate of the forward reaction is EQUAL TO the rate of the reverse reaction.

6.2
The balanced chemical equation is:
