How much heat is required to vaporize 1.00 mol of benzene, [tex]C_6H_6[/tex], at its boiling point? The heat of vaporization of benzene at its boiling point is 34.1 kJ/mol.

Select the correct answer below:

A. 34.1 kJ
B. 78.1 kJ
C. 156 kJ
D. 39.1 kJ

Answer :

Option (a), The heat required to vaporize 1.00 mol of benzene at its boiling point is 34.1 kJ/mol.

The heat of vaporization is the amount of heat required to transform a substance from the liquid state to the gas state.

The formula for the heat required to vaporize the benzene can be given as:

Q = n*ΔHvap

Where,

Q = heat required to vaporize the benzene

ΔHvap = heat of vaporization = 34.1 kJ/mol

n = number of moles = 1.00 mol

Now, substitute the values in the above equation:

Q = 1.00 mol x 34.1 kJ/mol

Q = 34.1 k

Option A is the correct answer.
