Question

The equilibrium constant `K_(c)` for the reaction `P_(4)(g) hArr 2P_(2)(g)` is `1.4` at `400^(@)C`. Suppose that 3 moles of `P_(4)(g)` and 2 moles of `P_(2)(g)` are mixed in 2 litre container at `400^(@)C`. What is the value of reaction quotient `(Q)` ?
A. `(3)/(2)`
B. `(2)/(3)`
C. 1
D. None of these

Answer 1

Correct Answer - 2
`Q_(c)=([p_(2)(g)]^(4))/([P_(4)(g)])=((1)^(2))/((3//2))=(2)/(3)`
