Question

Addition of water to which of the following equilibria causes it to shift in the backward direction

• A. $CH_{3}NH_{2} (aq) + H_{2}O(l) \rightleftharpoons CH_{3}NH_{3}(aq) + OH^{-} (aq)$
• B. $AgCl (s)\rightleftharpoons Ag^{+} (aq) + Cl^{-} (aq)$
• C. $HCN (aq) + H_{2}O(l) \rightleftharpoons H_{3}O^{+} (aq) + CN^{-} (aq)$
• D. $[Cr(dien)_{2}]^{3+} (aq) + 3H_{2}O (l) + 3Cl^{-} (aq) \rightleftharpoons [Cr(H_{2}O)_{3} Cl_{3}] (aq) + 2 \,dien\, (aq)$

Answer 1

Answer: (B)

Addition of Reactant causes the shift in forward Reaction. Addition of product cause the shift in backward Reaction. So, suitable option is B as Rest all are incorrect.
