A chemistry student needs to determine the effect of decreasing the temperature on the equilibrium position of the reaction N2(g) + 3H2(g) <-> 2NH3(g) if the initial concentrations of N2, H2 and NH3 are 0.4 M, 0.6 M, and 0.8 M respectively. How does the equilibrium concentration of NH3 change if the temperature is decreased from 400 K to 300 K, assuming constant volume and pressure?
