For `2HIhArrH_(2)+I_(2)`, the equilibrium constant is K. What is the equilibrium constant for `HIhArr1/2H_(2)+1/2I_(2)` at the same temperature?

Text Solution

Verified by Experts

For `2HIhArrH_(2)+I_(2)," "K=([H_(2)][I_(2)])/([HI]^(2))`
For `HIhArr1/2H_(2)+1/2I_(2)" "K^(1)=([H_(2)]^(1//2)[I_(2)]^(1//2))/([HI])`
`thereforeK^(1)=sqrtK`
