`A+B hArr C+D` is 100. If intially the concentrations of A and B are equal but at equilibrium concentration of D will be twice that of A, then what will be the equilibrium constant of the reaction ?A. `4//9`B. `0*18`C. `0*17`D. `0*11` |

Answer» Correct Answer - D `{:(,A,+,B,hArr,C,D,),(" Intial",a,,a,,,,),(" At eqm",(a-x),,(a-x),,x,,x):}` But we are given that `x= 2 (a-x)` or` 3 x = 2 a or a=3/2x = 1.5 x ` ` :. K= (x xx x)/(a-x^(2))= x^(2)/(1.5 x - x)^(2) = x^(2)/(0.25 x^(2))=4` |
