Question
Vapour density of PCl5 (g) dissociating into PCl3(g) and Cl2(g) is 100. Hence, van′t Hoff factor for the case :
PCl5(g) ⇋ PCl3(g) + Cl2(g) is
PCl5(g) ⇋ PCl3(g) + Cl2(g) is
Options
A.1.85
B.3.70
C.1.085
D.1.0425
Solution
PCl5 ⇋ PCl3 + Cl2
i = 1 + (y - 1) x = (1 + x)
x =
= 0.0425
∴ i = 1 + x = 1.0425
(D = theoretical VD =
d = experimental VD)
i = 1 + (y - 1) x = (1 + x)
x =
= 0.0425∴ i = 1 + x = 1.0425
(D = theoretical VD =
d = experimental VD)
