Chapter 5, Problem 5.88QP

Interpretation Introduction

Interpretation: The balanced chemical reaction for the decomposition of the ammonium nitrate above $300°\text{C}$ is to be written and the standard enthalpy of the reaction is to be calculated.

Concept introduction: The decomposition is a process in which any substance decomposes in to smaller fragments of another compound or form. The energy required for such decomposition is known as the enthalpy of the reaction. This is also known as heat of reaction and denoted by the symbol $\Delta H_{\text{reaction}}$. For the standard condition this is denoted by the symbol $\Delta H_{\text{reaction}}^{°}$. The standard heat of reaction is also defined as the enthalpy change during the transformation of matter in a specific chemical reaction. In such type of reactions all the reactants and the products should be in their standard state.

To determine: The balanced chemical reaction for the decomposition of the ammonium nitrate above $300°\text{C}$ and the standard enthalpy of reaction.
