The equilibrium constants for the reacti...

The equilibrium constants for the reactions X = 2Y and Z=P+Q are `K_(1) and K_(2)`, respectively. If the initial concentrations and the degree of dissociation of X and Z are the same, the ratio `K_(1)//k_92)` is

A

4

B

1

C

`0.5`

D

2

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(" "X,hArr,2Y,k_(1)," "Z,hArr,P+Q,k_(2)),(" "1,,0,," "1,,0" "0,),(1-alpha,,2alpha,,1-alpha,,alpha" "alpha,):}`
`(k_(1))/(k_(2))=(((2alpha)^(2))/((1-alpha)))/(((alpha^(2)))/((1-alpha)))=(4alpha^(2))/(alpha^(2))=4`
