When 3 moles of A and 1 mole of B are mixed in 1 litre vessel, the following reaction takes place `A_((g)) + B_((g))hArr2C_((g)). 1.5` moles of C are formed. The equilibrium constant for the reaction is

A

`0.12`

B

`0.25`

C

`0.50`

D

`4.0`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset((3-0.75))(A)+underset((1-0.75))(B)tounderset(1.5)(2C)`
`K=([C]^(2))/([A][B])=((1.5)^(2))/(2.25xx0.25)=(2.25)/(2.25xx0.25)=4.0.`
