For the reaction
`H_(2)(g)+CO_(2) (g)hArrCO(g)+H_(2)O(g),` if the initial concentration of`[H_(2)]=[CO_(2)]`and x moles /litres of hydrogen is consumed at equilibrium , the correct expression of `K_(p)` is :

A

`x^(2)/(1-x)^(2)`

B

`(1+x)^(2)/(1-x)^(2)`

C

`x^(2)/(2+x)^(2)`

D

`x^(2)/(1-x^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(2)(g) + CO_(2)(g) rarr CO(g) + H_(2)O(g)`
`K_(p) = x^(2)/(1-x)^(2)`
