Question

Which of the following comments about the following equilibrium reaction is the most correct?

$H_{2}S{O}_4\left(aq\right)+N{H}_3\left(aq\right)\rightleftharpoons HS{O}_4^{-}\left(aq\right)+N{H}_4^{+}\left(aq\right)$

• A. The equilibrium lies mostly to the right
• B. The equilibrium lies mostly to the left
• C. The equilibrium is exactly in between, where the concentration of each of the reactants is exactly equal to the concentration of each of the products
• D. The equilibrium depends on the temperature of the equilibrium reaction

Answer 1

The correct option is A The equilibrium lies mostly to the right

$H_{2}S{O}_4$ when dissolves & in water dissociate almost completely and produces $H^{+}$ ions. These ions are taken by $N{H}_3$ and its conjugate acid $N{H}_4^{+}$ is formed of $N{H}_3.$

Thus, the equilibrium lies mostly to right side or forward reaction.

$H_{2}S{O}_4\left(aq\right)+N{H}_3\left(aq\right)\rightleftharpoons HS{O}_4^{-}\left(aq\right)+N{H}_4^{+}\left(aq\right)$
