Question

The value of Kp for the reaction 2H2 O(g) + 2Cl2O(g) leftharpoons 4HCl (g) + O2 (g) is 0.03 atm at 427oC, when the partial pressures are expressed in atmosphere then the value of Kc for the same reaction is: (A) 5.23× 10-4 (B) 7.34 × 10-4 (C) 3.2 × 10-3 (D) 5.43 × 10-5

Kp = Kc (RT)1.,Kc = (0.03/(0.0821 ×700))1 =5.22 × 10-4

Q. The value of $K_{p}$ for the reaction
$2 H_{2} O (g) + 2 C l_{2} O (g) ⇌ 4 H Cl (g) + O_{2} (g)$ is $0.03 a t m$ at $42 7^{o} C$ , when the partial pressures are expressed in atmosphere then the value of $K_{c}$ for the same reaction is:

$5.23 \times 1 0^{- 4}$

$7.34 \times 1 0^{- 4}$

$3.2 \times 1 0^{- 3}$

$5.43 \times 1 0^{- 5}$

$K_{p} = K_{c} (RT)^{1} ., K_{c} = \frac{0.03}{( 0.0821 \times 700 )}^{1} = 5.22 \times 1 0^{- 4}$
