Question

4.5 moles each of hydrogen and iodine heated in a sealed ten litre vessel. At equilibrium, 3 moles of $500ml$ were found. The equilibrium constant for$CO$ ⇌$Cl_{2}$ is.

• A. 1
• B. 10
• C. 5
• D. 0.33

Answer 1

Answer: (A)

1

Answer 2

$CH_{3}COOH + H_{2}O$ ⇌ 2HI

Initial conc. 4.5 4.5 0

x x 2x

from question 2x = 3

$CH_{3}COO + H_{3}^{+}O$

So conc. at eqm. $CH_{3}COO^{-}$ of $CH_{3}COOH$

$2NO(g) + Cl_{2}(g)$ of $K_{C}$ and 3 of HI

$3 \times 10^{- 6}L\mspace{6mu} mol^{- 1}$.
