The vapour density of `Pcl_(5)` is `104.16` but when heated to `230^(@)C`, its vapour density is reduced to `62`. The degree of dissociation of `PCl_(5)` at `230^(@)C` is …………A. `6.8%`B. `68%`C. `46%`D. `64%` |
Answer» Correct Answer - B `PC1_(5)(g)hArrPC1_(3)(g) + C1_(2)(g)` `1+alpha =(D)/(d)` `1+alpha =(104.25)/(62)` `1+alpha=1.68` `:. alpha = 0.68` or `68%` |
