1.	At a certain temp. `HIhArrH_(2)+I_(2)` only `50%` HI is dissociated at equilibrium. The equiliium constant isA. `0.25`B. `1.0`C. `3.0`D. `0.50`
Answer» Correct Answer - A `underset(50)underset(100)(2HI)hArrunderset(25)underset(0)(H_(2))+underset(25)underset(0)(I_(2))` `([H_(2)][I_(2)])/([HI]^(2))=(25xx25)/(50xx50)=0.25.`
