In the combusion of 2g benzene, 2.5 kcal heat was evolved. What is the heat of combustion?

A

100 kcal

B

97.5 kcal

C

50 kcal

D

40 kcal

Text Solution

Verified by Experts

The correct Answer is:
B
Calorific value`=(2.5)/(2)`
`=1.25`k cal/g
Heat of combusion
`=1.25k` cal/g `xx78g`
`=97.5"k cal"`
