For the reaction `3A(g)+B(g) hArr 2C(g)` at a given temperature , `K_c=9.0`.What must be the volume of the flask, if a mixture of 2.0 mol each of A, B and C exist in equilibrium ?

Options

A. 6 L
B. 9 L
C. 36 L
D. None of these

Answer

A

Explanation

`K_c=([C/V]^2)/([B/V][A/V]^2) implies 9=([2/V]^2)/([2/V][2/V]^2) implies V=6L`
