Given the equilibrium equation: H2(g) + Br2(g) 2HBr(g) If the partial pressure of H2 is increased, the equilibrium will shift to the right. If the partial pressure of H2 is decreased, the equilibrium will shift to the left. If the partial pressure of HBr is increased, the equilibrium will shift to the left.
In exothermic reactions, increase in temperature decreases the equilibrium constant, K, whereas, in endothermic reactions, increase in temperature increases the K value. Le Chatelier's principle applied to changes in concentration or pressure can be understood by having K have a constant value. The effect of temperature on equilibria, however, involves a change in the equilibrium constant. The dependence of K on temperature is determined by the sign of Î´H.
