In a reaction `A+2B hArr 2C, ` 2.0 moles of `'A'` 3 moles of 'B' and 2.0 moles of 'C' are placed in a 2.0 L flask and the equilibrium concentration of 'C' is 0.5 mol`//` L . The equilibrium constant (K) for the reaction is

A

0.21

B

0.5

C

0.75

D

0.05

Text Solution

Verified by Experts

The correct Answer is:
D
`A + 2B rarr 2C`
`K_(c) = (1/2)^(2)/((4/2)^(2)(2.5/2)) = 1/4/(16/4 xx 2.5/2) = 0.05`
