Question

then
vap density of PCl5 at 200°c is
70.2 and at 250 °C is 57.9
what will be
be a at 200 °c &
250°C
A 48.5%, 80 % B) 70% ,80%
C)60 %.,70%
D) 80%,90/​

Answer 1

Answer:

When PCl5 is heated, it dissociates into PCl3 and Cl2. The vapour density of the gas mixture at 200∘C and at 250∘C is 70 and 58, respectively at the percentage of 60 and 70%
