JEE Main 2006 — Chemical Equilibrium Question with Solution
From: AIEEE 2006
Question
Phosphorus pentachloride dissociates as follows, in a closed reaction vessel
PCl5 (g) PCl3 (g) + Cl2 (g)
If total pressure at equilibrium of the reaction mixture is P and degree of dissociation of PCl5 is x, the partial pressure of PCl3 will be
PCl5 (g) PCl3 (g) + Cl2 (g)
