Interpretation Introduction

Interpretation:

The value of $\Delta$ H^o in kilojoules for the reaction needs to be determined.

${\text{3 N}}_{\text{2}}{\text{O}}_{\text{4}}\left(\text{g}\right){\text{ + 2 H}}_{\text{2}}\text{O }\left(\text{l}\right)\to {\text{4 HNO}}_{\text{3}}\left(\text{aq}\right)\text{ + 2 NO }\left(\text{g}\right)$

Concept introduction:

The heat change of a compound, when one mole of substance is produced from its constituents’ elements under standard conditions of temperature and pressure is known as standard heat of formation.
