SO2Cl2(g)SO2(g)+Cl2(g) a. Write the equilibrium expression, Kc, for the reaction. b. Suppose you start out with only reactants in a rigid container. If the initial concentration of SO2Cl2(g) is 0.543M, and 43.6% of this initial concentration remains when the system has reached equilibrium, what are the equilibrium concentrations of each gas in the system? (Hint: Use an ICE chart) c. What is the value of the equilibrium constant, Kc
