Question

The total vapour pressure of equimolar solution of benzene and toluene is given by `P_(T)` (in mm Hg) `=600-400X_("toluene")` then:
A. `p_("benzene")=200mmHg`
B. `p_("benzene")^(0)=600mmHg`
C. `p_("toluene")^(0)=200mmHg`
D. `p_("toluene")^(0)=600mmHg`

Answer 1

Correct Answer - B::C
for `p_("toluene")^(0)` , `X_("toluene")=1`
Then `P_("toluene")=200`
& for `P_("Benzene"), X_("benzene")=1&X_("toluene")=0`
So `P_("Benzene")=600`
