The equilibrium constant K(c) for the re...

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_(c))` ?

A

`(3)/(2)`

B

`(2)/(3)`

C

1

D

`(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Q_(c)=([P_(2(g))]^(2))/([P_(4(g))])=((1)^(2))/(3//2)=(2)/(3)`
