Interpretation Introduction

Interpretation:

The standard enthalpy change of the reaction is to be calculated.

Concept introduction:

The enthalpy of a reactionthattakes place at standard conditions is known as the standard enthalpy of the reaction.

The standard enthalpy of formation of a compound is defined as the amount of heat change involved when 1mole of a particular compound is formed from its constituent elements in their standard states.

The standard enthalpy of formation of an element in its standard or most stable state is zero.

Enthalpy change of a reaction is the difference of “sum of enthalpy change of the products” and “sum of enthalpy change of the reactants.”
