An aqueous solution containing a nonvolatile solute is heated in an open vessel till the boiling point is reached. Thereafter, the boiling is continued and the temperature and the vapour pressure of the solution are recorded at 5 ~min , 10 ~min , and 15 min . The corresponding temperatures and pressures are T₅, T₁₀, T₁₅ and P₅, P₁₀, P₁₅ , respectively. The correct relationship among them is:

Options

  1. AT₅ T₁₀ T₁₅ and P₅=P₁₀=P₁₅
  2. BT₅=T₁₀=T₁₅ and P₅=P₁₀=P₁₅
  3. CT₅=T₁₀=T₁₅ and P₅ P₁₀ P₁₅
  4. DT₅ T₁₀ T₁₅ and P₅ P₁₀ P₁₅

Correct answer

A. T₅ T₁₀ T₁₅ and P₅=P₁₀=P₁₅
