Chapter 9, Problem 9.116SP

Interpretation Introduction

(a)

Interpretation:

The standard enthalpy of reaction in kilojoule for the following process needs to be determined.

$\text{C }\left(\text{S}\right){\text{ + CO}}_{\text{2}}\left(\text{g}\right)\to \text{2CO }\left(\text{g}\right)$

Concept introduction:

The heat change of a compound, when one mole of substance is produced from its constituents’ elements under standard conditions of temperature and pressure is known as Standard heat of formation.

Interpretation Introduction

(b)

Interpretation:

The standard enthalpy of reaction in kilojoule for the following process needs to be determined.

${\text{2H}}_{\text{2}}{\text{O}}_{\text{2}}\left(\text{aq}\right)\to {\text{2H}}_{\text{2}}\text{O }\left(\text{l}\right){\text{ + O}}_{\text{2}}\left(\text{g}\right)$

Concept introduction:

The heat change of a compound, when one mole of substance is produced from its constituents’ elements under standard conditions of temperature and pressure is known as Standard heat of formation.

Interpretation Introduction

(c)

Interpretation:

The standard enthalpy of reaction in kilojoule for the following process needs to be determined.

${\text{Fe}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\text{ + 3 CO}\left(\text{g}\right)\to \text{2 Fe }\left(\text{S}\right){\text{ + 3CO}}_{\text{2}}\text{(g)}$

Concept introduction:
