Question

The reaction `A(g) + B(g)hArr2C (g)` is occurred by mixing of 3 moles of A and 1 mole of B in one litre container. If a of B is `(1)/(3)` , then `K_(c)` for this reaction is:
A. `0.12`
B. `0.25`
C. `0.50`
D. `0.75`

Answer 1

Correct Answer - B
`{:(,,,A(g),+,B(g),hArr,2C(g)),(t=0,,,3M,,1M,,),(t=oo,,,3-1/2,,1-1/3,,2/3):}`
`K_(C) = ((2//3)^(2))/((8//3)(2//3)) =(1)/(4) =0.25`
