Answer with explanation and you’ll get brain list

A

Explanation: It is A because if you calculate it you would see that it is A

The boiling point of benzene at given external pressure is 162.45°C

Explanation:

To calculate the boiling point of benzene, we use the Clausius-Clayperon equation, which is:

where,

= initial pressure which is the pressure at normal boiling point = 760 torr

= final pressure which is external pressure = 5500 torr

= Enthalpy of vaporization = 30.72 kJ/mol = 30720 J/mol     (Conversion factor: 1 kJ = 1000 J)

R = Gas constant = 8.314 J/mol K

= initial temperature or normal boiling pont =

= final temperature = ?

Putting values in above equation, we get:

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

Hence, the boiling point of benzene at given external pressure is 162.45°C
