In which of the following reactions the increase in pressure will favour the increase in products?

Question

Professor PC Thomas Classes · Answer

(b) : In reaction, $\mathrm{PCl}_{3(\mathrm{~g})}+\mathrm{Cl}_{2(\mathrm{~g})} \rightleftharpoons \mathrm{PCl}_{5(\mathrm{~g})}$ when pressure is increased the reaction goes in the forward direction because the number of moles of gas decrease in the forward direction. This is in accordance with the Le Chatelier's principle.
