Answer
(a) The reaction will shift right side.
(b) The reaction will shift left side.
(c) The equilibrium will not shift in any side.
Work Step by Step
(a)An increase in volume decreases the pressure.
According to Le Chatelier’s principle, an decrease in pressure causes a shift towards the side with more particles(moles).
(b) A decrease in volume will increases pressure.
According to Le Chatelier’s principle, an increase in pressure causes a shift towards the side with fewer particles(moles).
(c) According to Le Chatelier’s Principle, an increase in pressure causes a shift towards the side with fewer particles.
Both sides will have the same number of particles so there will be no effect.
