Question

Quizplus · Accepted Answer

The normal boiling point occurs when the vapor pressure equals the atmospheric pressure of 760 mmHg. Therefore, we can find the normal boiling point by reading the graph where the vapor pressure is 760 mmHg. From the graph, we can see that the vapor pressure of CHCl₃ is 760 mmHg at approximately 64°C. Therefore, the answer is D, 64°C.
