Question

Some gaseous equilibrium are given below:
`CO + H_(2)OhArrCO_(2) + H_(2)`
`2CO + O_(2)hArr2CO_(2)`
`2H_(2) + O_(2)hArr 2H_(2)O`
find out the realation between equilibrium constants:
A. `K = K_(1)K_(2)`
B. `K = (K_(1)K_(2))^(2)`
C. `K = (K_(1)K_(2))^(-1//2)`
D. `K = (K_(1)K_(2))^(1//2)`

Answer 1

Correct Answer - D
(1) `CO + H_(2)hArrCO_(2) + H_(2)`
(2) `2CO + O_(2)hAr2CO_(2)`
(3) `2H_(2) + O_(2)hAr2H_(2)O`
By subtraction (2) - (3) we get:
`2H_(2)O + 2COhArCO_(2) + H_(2)O`
`K = ((K_(1))/(K_(2)))^(1//2)`
