Answer» 0.331 M 0.033 M 0.133 M 1.33 M Solution :`A_(2)+B_(2) harr C_(2)+D_(2)` at t=0, `0.1""0.1""0.1""0.1` `Q=1 gt Kimplies` reaction PROCEEDS BACKWARD at eqm `0.1+x""0.1-x""0.1-x` `K=(1)/(4)=((0.1-x)^(2))/((0.1+x)^(2)) implies (1)/(2)=(0.1-x)/(0.1+x) implies x=(0.1)/(3)` `implies [A]_("eqm")=0.1+(0.1)/(3)=(0.4)/(3)=0.133M`
