During the Contact Process SO3 is produced from SO2 in a reversible reaction: 2SO2(g)+O2(g)2SO3(g) Write an expression for the equilibrium constant, Kc, and derive its units. When the equilibrium was established at 1000K; the following concentrations were found: 1.00moldm3SO20.2moldm3O21.3moldm3SO3 Calculate Kc at this temperature. What does the magnitude of Kc tell you about the proportion of reactants to products at equilibrium? Explain your
