The answer to each of the folowing questions is a single digit integar, ranging from 0 to 9. If the correct answers to the question numbers A, B, C and D (say) are 4,0,9 and 2 respectively , then the correct darkening of bubbles should be as shown on the side :
Equilibrium constant for the reaction `A_(3) (g) + 3 B_(2) (g) hArr 3 AB_(2) (g) " is " 64*0 "Then the equilibrium constant for the reaction " 1/3 A_(3) (g) + B_(2) (g) hArr AB_(2)(g) ` will be

Answer

4

Explanation

For `A_(3) + 3 B_(2) hArr 2 AB_(2), K=([AB_(2)]^(3))/([A_(3)][B_(2)]^(3))`
` 1/3 A_(3)+ B_(2) hArr AB_(2) K'=([AB_(2)]^(3))/([A_(3)]^(1//3)[B_(2)])`
`(K)^(1//3) = (64)^(1//3) = 4.`
