(a)

Interpretation Introduction

Interpretation:

The standard enthalpy of decomposition of Hydrazine has to be calculated. The equation has to be balanced and ΔH° has to be calculated in mass per kilogram for each of them and better fuel has to be identified.

Concept Introduction:

The change in enthalpy that is associated with the formation of one mole of a substance from its related elements being in standard state is called standard enthalpy of formation (ΔHf°).  The standard enthalpy of formation is used to determine the standard enthalpies of compound and element.

The standard enthalpy of reaction is the enthalpy of reaction that takes place under standard conditions.

The equation for determining the standard enthalpies of compound and element can be given by,

ΔH°reaction=nΔH°f(products)-mΔH°f(reactants)
