Question

Consider the following figure for the reaction :

A+B⟶M+N

$\Delta H$ or heat of reaction is _________ .

Answer 1

The heat of reaction is the amount of energy released or absorbed on total reaction is known as the heat of reaction.

$\to$ It is the difference in the energy levels of products and reactants.

$\Delta H=$Energy pf reactant- energy of product.

$\Delta H=Y+Z-Z=Y$

$\to$ $\Delta H$ or heat of reaction is $Y.$
