The equlibrium constant at 298 K for a reaction `A+BhArr C+D` is 100. If th initial concentration of all the foru species whre 1 M each, then equlibrium concentration of D (in mol`L^(-1))`will beA. `0.818`B. `1.818`C. `1.182`D. `0.182`

Answer» Correct Answer - B
`A+BhArrC+D`
`{:(t=0,1,1,1,1),(t_(eq),1-x,1-x,1+x,1+x):}`
`implies((1+x)^(2))/((1-x)^(2))=100" "implies(1+x)/(1-x)=10`
`implies1+x=10-10ximplies11x=9`
`impliesx=9/11implies[D]=1+9/11implies[D]=1.818`
