The heat evolved in combustion of benzene is given by the following equation :
`C_(6)H_(6)+15//2O_(2)to3H_(2)O+6CO_(2)` : `DeltaH=-3264.6 kJ`
Which of the following quantities of heat will be evolved when `39g` of benzene are burnt in an open container ?

A

816.15 kJ

B

1632.3 kJ

C

6528.2 kJ

D

2448.45 kJ

Text Solution

Verified by Experts

The correct Answer is:
B
78g of benzene on combustion produces
heat =-3264.6 kJ
`therefore " 39 g will produce = "(-3264.6)/(2)=-1632.3 kJ`.
