Use the graph of vapor pressure to determine the normal boiling point of CHCl₃. A)19°C B)52°C C)60°C D)64°C E)70°C

Question

Quizplus · Accepted Answer

The normal boiling point is the temperature at which the vapor pressure of the liquid equals the external pressure. From the graph, we can see that the vapor pressure of CHCl₃ is equal to 1 atm at around 64°C. Therefore, the normal boiling point of CHCl₃ is 64°C, so the best choice is D.
