Question

In which of the following equilibria, the value of $K_{c}$ is less than $K_{p} = K_{e}$ .

• A. $CH_{3}COOH + H_{2}O$ ⇌ $CH_{3}COO + H_{3}^{+}O$
• B. $CH_{3}COO^{-}$⇌$CH_{3}COOH$
• C. $2NO(g) + Cl_{2}(g)$ ⇌ $K_{C}$
• D. $3 \times 10^{- 6}$⇌ $- 1$

Answer 1

Answer: (B)

$CH_{3}COO^{-}$⇌$CH_{3}COOH$

Answer 2

$K_{c}$; When $NH_{4}HS$,

i.e. negative, $NH_{3}$.
