Chapter 12, Problem 85QRT

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the reaction of lime production by heating limestone has to be written.

(b)

Interpretation Introduction

Interpretation:

The sign of enthalpy of reaction of lime production from limestone has to be given.

(c)

Interpretation Introduction

Interpretation:

The enthalpy change of a reaction of lime production from limestone has to be calculated.

Concept Introduction:

Hess's Law:

The enthalpy change of given reaction is calculated by subtraction of sum of enthalpy of formation reactants from sum of enthalpy of formation reactant products.

  ${\text{ΔH}}_{\text{rex}}\text{=}{\displaystyle \sum {\text{ΔH}}_{\text{product}}}\text{-}{\displaystyle \sum {\text{ΔH}}_{\text{reactant}}}$

(d)

Interpretation Introduction

Interpretation:

The effect entropy for reaction of lime production from limestone has to be predicted.

Concept Introduction:

If number of mole increases result the increasing entropy value and decreases result the decreasing entropy of reaction.

(e)

Interpretation Introduction

Interpretation:

The given reaction favored by entropy, energy, both, or neither has to be given.

Concept Introduction:

If number of mole increases result the increasing entropy value and decreases result the decreasing entropy of reaction.

If number of mole increases result the increasing entropy value and decreases result the decreasing entropy of reaction.

(f)

Interpretation Introduction

Interpretation:

Reason for limestone must be heated to make lime has to be explained in terms of Le Chatelier's principle.

Concept Introduction:

Le Chatelier's principle:

It states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
