In which of the following equilibrium system is the rate of the backwa – InterviewSolution

1.	In which of the following equilibrium system is the rate of the backward reaction favoured by increase of pressure
Answer» `N_(2) + 3H_(2) hArr 2NH_(3)` `N_(2) + O_(2) hArr 2NO` `PCl_(5) hArr PCl_(3) + Cl_(2)` `2SO_(2) + O_(2) hArr 2SO_(3)` Solution :ACCORDING to Le Chatelier's principle if the pressure is increased, reaction will take place in a DIRECTION which will bring about a lowering of vapour pressure. This implies that equilibrium will SHIFT in the direction which produces the smaller NUMBER of gas molecules
