Chapter 7, Problem 3MCP

(a)

Interpretation Introduction

Interpretation:

Given reaction is exothermic or endothermic has to be identified.

    2CO(g)+O2(g)2CO2(g)+Energy

(a)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

From the given equation, it is understood that heat energy is released.  Therefore, this is an exothermic reaction.  Heat is released to the surroundings.

(b)

Interpretation Introduction

Interpretation:

Sign of enthalpy of the given reaction has to be identified.

    2CO(g)+O2(g)2CO2(g)+Energy

(b)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

The reaction given is found to be an exothermic reaction.  This means the enthalpy of reactants will be less than that of product.  Therefore, enthalpy of the reaction will be negative.

(c)

Interpretation Introduction

Interpretation:

Meaning and significance of enthalpy has to be given.

    2CO(g)+O2(g)2CO2(g)+Energy

(c)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

The reaction given is found to be an exothermic reaction.  This means the enthalpy of reactants will be less than that of product.  Therefore, enthalpy of the reaction will be negative.  Enthalpy is the term that is used to represent heat.  The sign of enthalpy gives information that the reaction is exothermic or endothermic.

(d)

Interpretation Introduction

Interpretation:

Sign of entropy of the given reaction has to be identified.

    2CO(g)+O2(g)2CO2(g)+Energy

(d)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

Entropy is the measure of randomness or disorder in a system.  Physical state of the reactant and product are gas only.  Therefore, there will not be any change in entropy.

(e)

Interpretation Introduction

Interpretation:

Meaning and significance of entropy has to be given.

    2CO(g)+O2(g)2CO2(g)+Energy

(e)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

Entropy is the measure of randomness or disorder in a system.  Physical state of the reactant and product are gas.  Therefore, there is no change in entropy.  This means the reaction is completely dependent on enthalpy.

(f)

Interpretation Introduction

Interpretation:

The reaction given will be spontaneous or nonspontaneous has to be identified.

    2CO(g)+O2(g)2CO2(g)+Energy

(f)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

It is known that change in enthalpy of the reaction is negative.  This means the reaction is exothermic.  Therefore, the given reaction is nonspontaneous because change in entropy is zero.

(g)

Interpretation Introduction

Interpretation:

Reaction will be slow or fast if the rate constant of the reaction is small has to be predicted.

    2CO(g)+O2(g)2CO2(g)+Energy

(g)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

Larger rate constant value means the reaction will be relatively fast.  This is because the concentration of the reactant will be more and there will be increased collision.  As the rate constant given for the reaction is small, the reaction will be slow one.

(h)

Interpretation Introduction

Interpretation:

One strategy for increasing the rate of the reaction has to be given.

    2CO(g)+O2(g)2CO2(g)+Energy

(h)

Expert Solution
Check Mark

Explanation of Solution

Given reaction is,

    2CO(g)+O2(g)2CO2(g)+Energy

Given reaction is an exothermic reaction.  Decreasing the temperature may increase the rate of the reaction.  Other possibility is to increase the pressure.  As per LeChatelier’s principle, increasing the pressure results in shifting of equilibrium towards fewer moles of gas.  Therefore, the rate of this reaction is increased.
