Chapter 5, Problem 5I.27E

(a)

Interpretation Introduction

Interpretation:

The below reaction is at equilibrium or not has to be determined.

  PCl3(g)+Cl2(g)PCl5(g),Kc=0.56

Concept Introduction:

Consider a gaseous reaction of the form as given below.

  aA(g)+bB(g)cC(g)+dD(g)

The expression of the reaction quotient can be written as given below.

  Qc=[C]c[D]d[A]a[B]b

Where, [C] and [D] are concentrations of product C and D and [A] and [B] are concentrations of reactant A and B.

Direction of a reaction:

  • If Q < K, the reaction has tendency to proceed toward products.
  • If Q = K, the reaction has achieved the equilibrium position.
  • If Q > K, the reaction has tendency to proceed toward reactants.

Where, Q is reaction quotient.

(a)

Expert Solution
Check Mark

Explanation of Solution

The required reaction is given below.

  PCl3(g)+Cl2(g)PCl5(g),Kc=0.56

The expression for reaction quotient for the above reaction can be written as shown below,

  Qc=[PCl5][PCl3][Cl2]

The concentrations of each substance can be calculated as given below.

  [PCl5]=MolesVolume=1.50mol0.500L=3M[PCl3]=MolesVolume=3.00mol0.500L=6M[Cl2]=MolesVolume=0.500mol0.500L=1M

By plugging all data in the above equation, the value of Q can be calculated as given below.

  Qc=[PCl5][PCl3][Cl2]Qc=3(6)(1)Qc=0.5

Therefore, the reaction quotient for PCl3(g)+Cl2(g)PCl5(g) is 0.5.

Here, QK.  So the reaction is not at equilibrium.

(b)

Interpretation Introduction

Interpretation:

The direction of the reaction PCl3(g)+Cl2(g)PCl5(g) has to be determined.

Concept Introduction:

Refer to part (a).

(b)

Expert Solution
Check Mark

Explanation of Solution

The required reaction is given below.

  PCl3(g)+Cl2(g)PCl5(g),Kc=0.56

The value of Q for the reaction is 0.5.

Therefore, Qc<K.  So the reaction will proceed to form products.

(c)

Interpretation Introduction

Interpretation:

The equilibrium composition of the reaction PCl3(g)+Cl2(g)PCl5(g) has to be determined.

(c)

Expert Solution
Check Mark

Explanation of Solution

The concentrations of each substance can be calculated as given below.

  [PCl5]=MolesVolume=1.50mol0.500L=3M[PCl3]=MolesVolume=3.00mol0.500L=6M[Cl2]=MolesVolume=0.500mol0.500L=1M

An equilibrium table can be set up as given below.

  Composition(M)PCl3Cl2PCl5Initialconcentration613Changeinconcentrationxx+xEquilibriumconcentration6x1x3+x

Now, these values in the fourth row can be inserted in the equilibrium constant expression as shown below.

  Kc=(3+x)(6x)(1x)

Now, the equilibrium constant expression can be solved for x.

  Kc=(3+x)(6x)(1x)0.56=(3+x)(6x)(1x)0.56x24.92x+0.36=0x=(4.92)±(4.92)24×(0.56)×(0.36)2×0.56x=0.071[PCl5]=3+x=3.07mol.L-1[PCl3]=6-x=5.93mol.L-1[Cl2]=1x=0.93mol.L-1

Therefore, the equilibrium composition of the reaction is [PCl5]=3.07mol.L-1,[PCl3]=5.93mol.L-1,and[Cl2]=0.93mol.L.
