 (a)

Interpretation Introduction

Interpretation:

For the given molecule sign, the magnitude of $\text{ΔΗ}$ (Enthalpy) to be determined and also the reaction should be classified as exothermic or endothermic

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.
