The following reaction was performed in a sealed vessel at 716°C : H2(g)+I2(g)?2HI(g) Initially, only H2 and I2 were present at concentrations of [H2]=3.40M and [I2]=2.30M. The equilibrium concentration of I2 is 0.0900M . What is the equilibrium constant, Kc, for the reaction at this temperature? CO(g)+Cl2(g)?COCl2(g) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 475°C . At equilibrium, the concentrations were measured and the following results obtained: Gas Partial Pressure (atm) CO 0.900 Cl2 1.30 COCl2 0.240 What is the equilibrium constant, Kp, of this reaction?
