If excess F_(2)(g) reacts at 0^(@)C and 1.0 atm pressure with Br_(2)(g) to give a compound BrF_(n), if 224ml of Br_(2)(g) at the same temperature and pressure produced 3.5g of BrF_(n), what is n? |

Answer» SOLUTION :`Br_(2)+nF_(2)rarr2BrF_(n)` `224 ML Br_(2)` at 273 K and 1 ATM `n_(Br_(2))=((1)(224)xx10^(-3))/(0.0821xx273)=0.01` mol `n_(Br)F_(n)=2n_(Br_(2))=0.02` mol `(3.5)/((80+19n))=0.2` 3.5=1.6+0.38n 1.9=0.38n `n=(1.9)/(0.38)=5` |
