If the value of equilibrium constant 1×10121 \times 10^{- 12} for the reaction, 3.8×1033.8 \times 10^{- 3} + 3.83.8 5.045.04 is 7. The equilibrium constant

for the reaction 2.422.42 9.29.2 will be

A

49

B

7

C

14

D

28

Answer

49

Explanation

Solution

: If reaction is multiplied by 2, the equilibrium constant becomes square of the previous valueK=72=49K = 7^{2} = 49
