Using the Le Chatelier's principle, predict the direction of the net reaction in each of the following equilibrium systems, as a result of increasing the pressure at constant temperature.
a)N2(g) + O2(g) ==> 2NO(g)
b)PCl5 ==> PCl3(g) + Cl2(g)
c)CO(g) + Cl2(g) ==> COCl2(g)
The reaction will shift to the side with fewer moles when the pressure is increased. For a there is no change. b is correct; c will go to the right.
