Enthalpy of combustion of C(6) H(6) (l) ...

Enthalpy of combustion of `C_(6) H_(6) (l)` is - 3264. 64 kj/ mol . The heat produced by burning 3. 9 g of benzene is

A

`-163.23 kJ`

B

`` 326 . 4 kJ

C

` 32.64 kJ`

D

`-3.254 kJ`

Text Solution

Verified by Experts

The correct Answer is:
a
since , heat evolved when 78 g benzene is burnt
`=-3264.6 kJ`
therefore, heat produced , by buring 3.9 g benzence
`3.9/78xx(-3264.6)=-163.23 kJ`
