NCERT · Class 11 · Chemistry · EquilibriumFor the gaseous equilibrium $PCl5(g) \rightleftharpoons PCl3(g) + Cl2(g)$, how will increasing total pressure affect the equilibrium?
Step-by-Step Solution
In this reaction, $\Delta n_g = 1 > 0$ (moles increase in forward reaction). Increasing total pressure shifts the equilibrium towards the side with fewer gaseous moles (backward direction).
