Question

Write equilibrium constant expression for following reactions:

(i) BaCO₃ (s) ⇌ BaO (s) + CO₂ (g)

(ii) AgBr (s) ⇌ Ag⁺ (aq) + Br^- (aq)

(iii) CH₃COCH₃ (1) ⇌ CH₃COCH₃ (g)

(iv) CH₄ (g) +20₂(g) ⇌ CO₂(g) + 2H₂O(l)

(v) HPO₄^2- (aq) + H₂O (1) ⇌ H₃O⁺ (aq) + PO₄^2- (aq)

(vi) AI (s) + 3H⁺ (aq) ⇌ Al³⁺ (aq) + \(\frac{3}{2}\)H₂ (g)

Answer 1

(i) K_p = p[CO₂]

(ii) K_c = [Ag+][Br-]

(iii) K_p = p[CH₃COCH₃]

(iv) K_p = \(\frac{(pCO_2)}{(pCO_4)(pCO_2)^2}\)

(v) K_c = \(\frac{[H_3O^+][PO^{2-}_4]}{[HPO^{2-}_3]}\)

(vi) K_c = \(\frac{[Al^{3+}][H_2(g)]^\frac{3}{2}}{[H^+]^3}\)
