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 isA. `0.12`B. `0.25`C. `0.50`D. `4.0`

Answer» Correct Answer - D
A + B `rarr` 2C
`(3-0.75)` `(1-0.75)` `1.5`
`K = ([C]^(2))/([A][B]) = ((1.5)^(2))/(2.25xx0.25) = (2.25)/(2.25xx0.25) = 4.0`
