Vapour pressure of a solution of heptane...

Vapour pressure of a solution of heptane and octane is given by the equation :
`P_("sol")(m m Hg) = 32 + 63x`
where `x` is the mole fraction of heptane. Vapour pressure of pure heptane will be

A

32 mm Hg

B

95 mm Hg

C

47.5 mm Hg

D

63 mm Hg

Text Solution

Verified by Experts

The correct Answer is:
B
For pure heptane, `x=1`
P (heptane)`=32+63+1=95` mm Hg
