Solution :
The process involved in this problem are :
The expression used will be:
where,
= heat released by the reaction = ?
m = mass of benzene = 125 g
= specific heat of gaseous benzene =
= specific heat of liquid benzene =
= enthalpy change for vaporization =
Molar mass of benzene = 78.11 g/mole
Now put all the given values in the above expression, we get:
Therefore, the energy removed must be, -67.7 kJ
