`C+O_(2) rarr CO_(2), Delta H =-396 kJ mol^(-1)`. Heat liberated in formation of 0.154 kg of `CO_(2)` is

A

1386 J

B

13.86 kJ

C

1386 kJ

D

138.6 kJ

Text Solution

Verified by Experts

The correct Answer is:
C
`0.044" kg of "CO_(2)` liberates 396 kJ heat.
`therefore 0.154" kg of "CO_(2)` liberates
`(0.154xx396)/(0.044)=1386` kJ heat
