AIPMT-MAIN Chemistry Equilibrium Class 11 Questions

Equal volumes of three acid solutions of pH 3, 4 and 5 are mixed in a vessel. What will be the H⁺ ion concentration in the mixture?

The values of Kₚ₁ and Kₚ₂ for the reactions X ⇌ Y + Z and A ⇌ 2B are in ratio of 9:1. If degree of dissociation of X and A be equal, then total pressure at equilibrium (1) and (2) are in the ratio

If the concentration of OH⁻ ions in the reaction Fe(OH)₃ (s) ⇌ Fe³⁺ (aq) + 3OH⁻ (aq) is decreased by 1/4 times, then equilibrium concentration of Fe³⁺ will increase by

For the gas phase reaction, PCl₅ (g) ⇌ PCl₃ (g) + Cl₂ (g) which of the following conditions is correct?

The dissociation equilibrium of a gas AB₂ can be represented as, 2AB₂ (g) ⇌ 2AB (g) + B₂ (g). The degree of dissociation is 'x' and is small compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant Kₚ and total pressure P is
