1.	Given the reaction between 2 gases represented by `A_(2) and B_(2)` to give the compound AD(g). `A_(2)(g)+B_(2)(g)hArr2AB(g).` At equilibrium, the concentration `of A_(2)=3.0xx10^(-3)M` `of B_(2)=4.2xx10^(-3)M` `of AB=2.8xx10^(-3)M` If the reaction takes place in a scaled vassel at `527^(@)C,` then the value of `K_(c)` will beA. `2.0`B. `1.9`C. `0.62`D. `4.5`
Answer» Correct Answer - C `A_(2)+B_(2)hArr2AB` `K_(C)=((2.8xx10^(-3))^(2))/(3xx10^(-3)xx4.2xx10^(-3))=((2.8))/(3xx4.2)=0.62`
