Consider the following reaction at equilibrium: 2502 (9) 02 (9) 250з (g) A H° = -99 kJ Le Châtelier's principle predicts that a(n) decrease in temperature will result in no changes in equilibrium partial pressures a decrease in the partial pressure of S03 an increase in the partial pressure of SO3 G an increase in the partial pressure of 02 • a(n) decrease in Keg
