Answer 1

a) HNO₃ (aq) = H⁺(aq) + NO₃^-(aq) This is a oneway forward reaction as HNO₃ is a strong acid so it will completely dissociate in aqueous solution.

b) Br^- (aq) + HOH (l) = HBr + OH^- (aq) Though this reaction is an acid base reaction but still it cannot occur as Br^- is a very weak base so it can not deprotonate water.

c) CH₃COOH (aq) + HOH (l) = CH₃COO^- (aq) + H⁺ (aq) This is a reaction that represents equilibrium as CH₃COOH is a weak acid so it will be in equilibrium with CH₃COO^- and H⁺ in aqueous solution.

d) CH₃COO^- (aq) +HOH (l) = CH₃COOH (aq) + OH^- (aq) This is an acid base reaction as CH₃COO^- (aq) reacts as a base to deprotonate water to form CH₃COOH (aq).

So c represents an equilibrium reaction, a represents a one way forward reaction, b represents a reaction that can never occur and both b and d represent an acid base reaction.
