Question

Choose the correct statement among the following:

i) Heat of reaction depends on the temperature at which the reaction is carried out.

ii) Heat of neutralisation depends on the temperature at which the experiment is carried out.

iii) Experimentally, heat of combustion is $\Delta E$.

• A. (i) only
• B. (iI) only
• C. (iii) only
• D. All are correct

Answer 1

The correct option is D All are correct

$\Delta H$ depends upon the temperature, therefore (i) and (ii) are correct.
iii) Experimentally, heat of combustion is $\Delta E$.
