A chemistry student wants to know how the equilibrium of a reaction will be affected by an increase in temperature. The reaction studied is N2(g) + 3H2(g) ↔ 2NH3(g) and has an equilibrium constant (Kc) of 3.5 x 10^-5 at a certain temperature. If the temperature is increased, what will happen to the concentration of NH3 at equilibrium?
