Interpretation Introduction

Interpretation:

For the given molecule sign and the magnitude of $\text{ΔΗ}$ (Enthalpy) and whether the reaction exothermic or endothermic should be identified

Concept introduction:

$\text{ΔΗ}$ (Enthalpy) can be determined by using following formula

$\text{ΔΗ}$ (Enthalpy of the reaction) = $\text{ΔΗ }\left(\text{bonds broken}\right)\text{ – ΔΗ (bonds formed)}$

$\text{ΔΗ}$ of the reaction is determined by bond breaks and bond formation of the reaction.

When the heat energy was absorbed by the system from the surrounding is called endothermic reaction

When heat energy or light energy was unconfined to the surrounding from the system is called exothermic reaction.
