In a gaseous reaction A+2B iff 2C+D the ...

In a gaseous reaction `A+2B iff 2C+D` the initial concentration of B was 1.5 times that of A. At equilibrium the concentration of A and D were equal. Calculate the equilibrium constant `K_(C)`.

Text Solution

Verified by Experts

`A + 2B rarr 2C + D`
Given, `a-x=2x implies x= a//3`
`Now, K_(c) = [C]^(2)[D]/([A][B]^(2)) = ((2a/3)^(3)xx a/3)/((a-a/3)(3a/2 - 2a/3)^(2)) = 0.32`
