When 3 moles of A and 1 mole of B are mixed in 1 litre vessel, the following reaction takes place `A_((g)) + B_((g))hArr2C_((g)). 1.5` moles of C are formed. The equilibrium constant for the reaction is

Options

A. 0.12
B. 0.5
C. 0.25
D. 4

Answer

D

Explanation

`{:(,A,+,B,hArr, 2C),("Initial moles",3,,1,,1.5),("Eqm. moles",2.25,,0.25,,1.5):}`
`K_(c)=((1.5)^(2))/(2.25xx0.25)=4.00`
