Consider the following equilibrium for which H = 75.54 kJ: 2 NOCl(g) 2 NO(g) + Cl2(g) If a mixture of the gases involved in this reaction is allowed to come to equilibrium, and some NOCl is removed from this equilibrium mixture, decreasing the partial pressure of NOCl, what will the reaction do in response to this change, and how will the value of K (the equilibrium constant) be affected? a) The reaction will shift toward products with no change in K. b) The reaction will shift toward products with a decrease in K. c) The reaction will shift toward products with an increase in K. d) The reaction will not shift and the value of K will not change. e) The reaction will shift toward reactants with no change in K.
