NEET · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)
Using the Gibb's energy change, \(\Delta G^o = +63.3 \,kJ,\) for the following reaction, \(Ag_2CO_{3(s)} \rightleftharpoons 2Ag^+_{(aq)} + CO^{2-}_{3(s)}\) in water at \(25\, ^o C\) is \((R = 8.314\, J\, K^{-1}\,mol^{-1})\)
- A \(3.2 \times 10^{-26}\)
- B \(8.0 \times 10^{-12}\)
- C \(2.9 \times 10^{-3}\)
- D \(7.9 \times 10^{-2}\)
Answer & Solution
Correct Answer
(B) \(8.0 \times 10^{-12}\)
Step-by-step Solution
Detailed explanation
\(\Delta \mathrm{G}^{o}\) is related to \(\mathrm{K}_{\mathrm{sp}}\) by the equation, \(\Delta G^{o}=-2.303 \mathrm{RT} \log \mathrm{K}_{\mathrm{sp}}\) We have Given, \(\Delta G^{o}=+63.3 \,\mathrm{KJ}=63.3 \times 10^{3} \,\mathrm{J}\)
