Chapter 20, Problem 40PS

Interpretation Introduction

Interpretation: The amount of coal burnt to produce the given amount of ${\text{SO}}_{\text{2}}$ has to be determined.

Concept introduction:

Enthalpy of combustion: At standard conditions when one mole of substance is burnt completely in presence of oxygen, the enthalpy change involved is called enthalpy of combustion.

${\text{ΔH}}^{\text{0}}{}_{\text{comb}}\text{=}\sum \text{n}{\text{ΔH}}^{\text{0}}{\text{f}}_{\text{products}}\text{-}\sum \text{n}{\text{ΔH}}^{\text{0}}{\text{f}}_{\text{reactants}}$

General unit conversion:

$\text{1}\text{Gg}\text{=}\text{1000}\text{ton}$
