Homework Answers
According to Le Chatelier's principle, the increase of pressure on system at equilibrium shifts the reaction towards the formation of less number of gaseous species.
A (g) + 2B (g) <-----> C (g)
Number of gaseous molecules on reactants side = 3
Number of gaseous molecules on products side = 1
So increase of pressure on above reaction favors formation of C.
The statement is true only if the number of moles of gaseous components on products side is lesser than the number of moles of gaseous components on reactants side.
