(a)

Interpretation Introduction

Interpretation:

Average rate of reaction in the interval 0.00 to 0.50 h has to be calculated.

Concept Introduction:

Consider the following reaction.

a A+b B→c C

Where A and B are reactants and C is the product. a,b and c are stoichiometric co-efficient of A,B and C.

rate=-1aΔ[A]Δt=-1bΔ[B]Δt=1cΔ[C]Δt

Where,

    −Δ[A]Δt= rate of disappearance of A

    −Δ[B]Δt= rate of disappearance of B

    Δ[C]Δt= rate of appearance of C

Rate of the reaction can be expressed in terms of change in concentration of reactant and products by multiplying the reciprocal of the corresponding stoichiometric co-efficient to that.

When the rate is expressed in terms of change in reactant concentration, a minus sign has to be given. Since change in time will be a positive quantity and reactant concentration decreases with time change in concentration of reactant will be negative. So in order to make the rate a positive quantity negative sign is given.

But if the rate is expressed in terms of change in concentration of products, which is a positive quantity, no need of negative sign in the rate expression.

When the rate is expressed in terms of change in reactant concentration, a minus sign has to be given. Since change in time will be a positive quantity and reactant concentration decreases with time change in concentration of reactant will be negative.

Answer to Problem 13QRT

Average rate is 0.120 mol L-1 h-1.

Explanation of Solution

Given that the concentration of N2O5 at t= 2 h is 0.473 mol/L and the concentration of N2O5 at t= 3.0 h is 0.352 mol/L.

So the average rate can be calculated as follows,

rate=change in concentrationchange in time =−[0.352 mol/L− 0.473 mol/L][3 h − 2 h] = 0.120 mol L-1 h-1.

So the average rate can be calculated as follows,

rate=change in concentrationchange in time =−[0.262 mol/L−0.352 mol/L][4 h − 3 h] = 0.090 mol L-1 h-1.

Average rate is 0.090 mol L-1 h-1.

So the average rate can be calculated as follows,

rate=change in concentrationchange in time =−[0.196 mol/L−0.262 mol/L][5 h − 4 h] = 0.066 mol L-1 h-1.

Average rate is 0.066 mol L-1 h-1.

Answer 6

Chapter 11, Problem 13QRT

(a)

Interpretation Introduction

Interpretation:

Average rate of reaction in the interval 0.00 to 0.50 h has to be calculated.

Concept Introduction:

Consider the following reaction.

a A+b B→c C

Where A and B are reactants and C is the product. a,b and c are stoichiometric co-efficient of A,B and C.

rate=-1aΔ[A]Δt=-1bΔ[B]Δt=1cΔ[C]Δt

Where,

    −Δ[A]Δt= rate of disappearance of A

    −Δ[B]Δt= rate of disappearance of B

    Δ[C]Δt= rate of appearance of C

Rate of the reaction can be expressed in terms of change in concentration of reactant and products by multiplying the reciprocal of the corresponding stoichiometric co-efficient to that.

When the rate is expressed in terms of change in reactant concentration, a minus sign has to be given. Since change in time will be a positive quantity and reactant concentration decreases with time change in concentration of reactant will be negative. So in order to make the rate a positive quantity negative sign is given.

But if the rate is expressed in terms of change in concentration of products, which is a positive quantity, no need of negative sign in the rate expression.

Expert Solution

Answer to Problem 13QRT

Average rate is 0.23 mol L-1 h-1.

Explanation of Solution

Given that the concentration of N2O5 at t= 0.00 h is 0.849 mol/L and the concentration of N2O5 at t= 0.50 h is 0.733 mol/L.

So the average rate can be calculated as follows,

rate=change in concentrationchange in time =−[0.733 mol/L−0.849 mol/L][ 0.50 h− 0.00 h] = 0.23 mol L-1 h-1.

Average rate is 0.23 mol L-1 h-1.
