Question

A solution consists of chloroform and acetone. At 300 K, the partial vapor pressure for chloroform/is 20.0 and 220.0 mmHg whe

Answer 1

Answer #1

Step 1: Calculation of total pressure

Total pressure = partial pressure of chloroform + partial pressure of acetone

Total pressure = 20 + 220 mm Hg = 240 mm Hg.

Step 2: calculation of partial pressure using mole fraction

Partial pressure of chloroform = mole fraction of chloroform X total pressure

Partial pressure of chloroform = 0.12 / 0.92 X 240

= 31.30 mm Hg.

The given partial pressure of chloroform is 20 mm Hg, but calculated partial pressure of chloroform is 31.30 mm Hg.

Since, there is a difference in mole fraction , the combination of solution is a real solution and not ideal solution.

Ideal Solutions maintain, same pressure, both theoritithe and calculated.
