Question

When 3 moles of A and 1 mole of B are mixed in 1 litre vessel the following reaction takes place `A_((b))+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`

Answer 1

Correct Answer - 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.`
