If the temperature of a liquid-vapor system at equilibrium increases, the new equilibrium condition will

nikdorinn [45]

If the temperature of a liquid-vapor system at equilibrium increases, it will shift towards the vapor phase, assuming that the pressure remains equal. The concentration of vapor will also increase relative to the concentration of liquid in the system. Thus, the new equilibrium condition will have more vapor than liquid.

Calculate mole fraction of benzene (70 g) having 30 gram of mass of carbon tetrahedral

Fynjy0 [20]

Moles of benzene

70/90=7/9=0.8mol

moles of CCl_4

30/154
0.2mol

Now

$\\ \rm\Rrightarrow \chi_{C_6H_6}$

$\\ \rm\Rrightarrow \dfrac{\chi_{C_6H_6}}{\chi_{sol^n}}$

$\\ \rm\Rrightarrow \dfrac{0.8}{0.8+0.2}$

$\\ \rm\Rrightarrow \dfrac{0.8}{1}$

$\\ \rm\Rrightarrow 0.8$
