In the following reaction started only with `A_(B), 2A_(B)(g) hArr3A_(2)(g)+A_(4)(g)` mole fraction of `A_(2)` is found to `0.36` at a total pressure of `100 atm` at equilibrium. The mole fraction of `A_(8)(g)` at equlibrium is `:`A. `0.28`B. `0.72`C. `0.18`D. None of these |

Answer» Correct Answer - 1 `{:(,2A_(B),hArr,2A_(3),+,3A_(2),+,A_(4)),(t=0,2,,0,,0,,0),(t=t_(aq),2-2alpha,,2alpha,,3alpha,,alpha):}` `n_(r)=2+4alpha` given mole fraction of `A_(2)` is `=0.36`. `0.36=(3alpha)/(2+4alpha)` `alpha=0.46` Mole fraction of `A_(B)=(2-2alpha)/(2+4alpha)=(2-2xx0.46)/(2+4xx0.46)=0.28` |
