Question
The value of KP for the reaction: H2(g) + I2(s) $\rightleftharpoons$2HI(g) is 6.4 × 10–4 atm. On close observation, it is found that the partial pressure of iodine present in vapour state is 1.6 × 10–4 atm, at the same temperature. The value of KP for the reaction: H2(g) + I2(g) $\rightleftharpoons$2HI(g) is
Options
A.0.25
B.4
C.1.024 × 10–7
D.9.76 × 106
Solution
H2(g) + I2(s) $\rightleftharpoons$2HI(g); Kp = 6.4 × 10–4 atm
I2(s) $\rightleftharpoons$I2(g); Kp = 1.6 × 10–4 atm
∴ H2(g) + I2(g) $\rightleftharpoons$2HI(g); $K_{p} = \frac{6.4 \times 10^{- 4}}{1.6 \times 10^{- 4}} = 4$
