Consider the reaction: P(s)+3/2Cl2(g)PCl3(g) Write the equilibrium constant for this reaction in terms of the equilibrium constants, K1 and K2, for the reactions below: P(s)+5/2Cl2(g)PCl5(g)K1PCl3(g)+Cl2(g)PCl5(g)K2 For answers with both a subscript and a superscript, enter the subscript first. For example, enter K12 if the first equilibrium constant should be squared
