If the heat formation of `CO_(2)` is -393kJ. The amount of heat evolved in the formation of 0.176 kg of `CO_(2)` is

A

`-1357.9`kJ

B

`-1275.9` kJ

C

`-1572.0` kJ

D

`-1165.5` kJ

Text Solution

Verified by Experts

The correct Answer is:
C
Heat of formation of a substance is the heat exchanged when one mole of that substance is formed by its constituent elements.
`because` Heat evolved when 1 mole (44g) `CO_(2)` is formed
`=(393xx156)/(44)`
`therefore DeltaH` for the process = 1572 kJ =-1572.0 kJ`.
