In the reaction `AB_((g))hArrA_((g))+B_((g))at 30^(@)C, K_(p)` for the dissociation equlibrium is `2.56xx10^(-2)` atm. If the total pressure at equlibrium is I atm, then the precentage dissociation of ABA. `87%`B. `13%`C. `43.5%`D. `6%` |

Answer» `AB_((g)) to A_((g))+B_((g))` Applying law of mass action `K_(p)=(alpha^(2)P)/(a-alpha^(2))` `(alpha^(2))/(1-alpha)=2.56xx10^(-2)" "[therefore(1-alpha)=1]` `impliesalpha^(2)=2.56xx10^(-2)` `impliesalpha=sqrt(2.56xx10^(-2))impliesalpha=0.16` `%` age dissociation `=16%` |
