Question -
Answer -
(a) The number of moles ofreaction products will increase. According to Le Chatelier’s principle, ifpressure is decreased, then the equilibrium shifts in the direction in whichthe number of moles of gases is more. In the given reaction, the number ofmoles of gaseous products is more than that of gaseous reactants. Thus, thereaction will proceed in the forward direction. As a result, the number ofmoles of reaction products will increase.
(b) The number of moles ofreaction products will decrease.
(c) The number of moles of reaction productsremains the same.
