Chemical Equilibrium

 

22)  PPCl3 = 0.124 atm          PCl2 = 0.157 atm          PPCl5 = 1.30 atm          T = 450 K

 

       PCl3(g) + Cl2(g) PCl5(g)

      
       (a) Keq = PPCl5/(PPCl3 x PCl2) = 1.30/(0.124 x 0.157) = 66.8

 

       (b) Because Keq >>> 1, the formation of PCl5 is favored over the reactants.
