C+O(2) rarr CO(2), Delta H =-93 kJ, for ...

`C+O_(2) rarr CO_(2), Delta H =-93 kJ`, for formation of 11 mg of `CO_(2)` is

A

-0.92 kJ

B

-0.02325 kJ

C

-0.69 kJ

D

- 0.82 kJ

Text Solution

Verified by Experts

The correct Answer is:
B
Molar mass of `CO_(2) =44" i.e. for "44 g CO_(2)` heat of formation `(Delta H_(f))` is - 93 kJ, then for 11 mg i.e. `0.25xx10^(-3) g`, the heat released will be -0.02325 kJ.
