Chapter 4.10, Problem 4.13PSP

Interpretation Introduction

Interpretation:

The amount of energy transferred during explosion of $10g$ Nitroglycerin has to be calculated.

Concept Introduction:

The energy tends to change and continuously gets transferred into the system or out from the system to surroundings since the nanoscale particles possess higher potential energy in one phase than the other phase.

Enthalpy is the amount energy absorbed or released in a process.

The enthalpy change in a system ${\text{(ΔΗ}}_{\text{rxn}}\text{)}$ can be calculated by the following equation.

  ${\text{ΔH}}_{\text{rxn}}{\text{ = ΔH}}^{\text{°}}{}_{\text{produdcts}}{\text{- ΔH}}^{\text{°}}{}_{\text{reactants}}$

Where,

  ${\text{ΔH}}^{\text{°}}{}_{\text{reactants}}$ is the standard entropy of the reactants

  ${\text{ΔH}}^{\text{°}}{}_{\text{produdcts}}$ is the standard entropy of the products
