The two common chlorides of phosphorus, pcl3, and pcl5, both important for the production of the other phosphorus compounds, coexist in equilibrium through the reactionpcl3(g) + cl2(g) = pcl5(g)at 250 ᵒc , an equilibrium mixture in a 25.0 l flask contains 0.105 g pcl5, 0.220 g pcl3 and 2.12 g of cl2. what are the values of(a) kc(b) kp for this reaction at 250 ᵒc ?
