Answer : The reactant acid and conjugate base in this reaction is, $NH_4^$ and $NH_3$ .

Explanation :

Conjugate acid : A species that is formed by receiving of a proton $(H^+)$ by a base is known as conjugate acid.

Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.

The given chemical reaction is,

$CH_3COO^-+NH_4^+\rightleftharpoons CH_3COOH+NH_3$

In this reaction, $CH_3COO^-$ (base) react with $NH_4^$ (acid) to give $CH_3COOH$ (conjugate acid) and $NH_3$ (conjugate base).

Therefore, the reactant acid and conjugate base in this reaction is, $NH_4^$ and $NH_3$ .
