Question

The enthalpy of Vapourisation of cely is 30.5 komol'
Calculate the heat required for the Vapouriseton
of 284 gr. of cely at constant pressure.​

Answer 1

Answer:

Given that

enthalpy of vaporization of 1 mole of CCl

4

=30.5kJ/mol.

It means 1

mole of CCl

4

=154g

154g requires heat of vaporization =30.5kJ/mol

∴

Heat required for vapourisation of 284g of CCl

4

=

154gmol

−1

284g

×30.5kJ/mol

−1

=56.2KJ
