Chapter 4, Problem 4E.2AST
Interpretation Introduction

Interpretation:

The standard reaction enthalpy for the given reaction has to be determined.

Concept Introduction:

The bond enthalpy is the physical quantity use to measure the strength of chemical bond.  The reaction enthalpy of a reaction in terms of the bond enthalpies is the difference between the standard bond enthalpies reactant and that of the product.  The breaking of bond is always the endothermic process however the formation of bond is the exothermic process.

Explanation of Solution

The given chemical reaction for which reaction enthalpy has to be calculated is shown below.

  CCl3CHCl2(g)+2HF(g)CCl3CHF2(g)+2HCl(g)

The total bond enthalpy of reactants of the given reaction is calculated by the relation shown below.

    ΔHB°(reactants)=((1mol)ΔHB(CH)+(5mol)ΔHB(CCl)+(1mol)ΔHB(CC)+(2mol)ΔHB(HF))        (1)

Where,

  • ΔHB°(reactants) is total bond enthalpy of reactants.
  • ΔHB(CH) is bond enthalpy of CH bond.
  • ΔHB(CCl) is bond enthalpy of CCl bond.
  • ΔHB(CC) is bond enthalpy of CC bond.
  • ΔHB(HF) is bond enthalpy of HF bond.

The value of ΔHB(CH) is 412kJmol1.

The value of ΔHB(CCl) is 338kJmol1.

The value of ΔHB(CC) is 348kJmol1.

The value of ΔHB(HF) is 565kJmol1.

Substitute the value of ΔHB(CH), ΔHB(CCl), ΔHB(CC) and ΔHB(HF) in equation (1).

  ΔHB°(reactants)=((1mol)×(412kJmol1)+(5mol)×(338kJmol1)+(1mol)×(348kJmol1)+(2mol)×(565kJmol1))=412kJ+1690kJ+348kJ+1130kJ=3580kJ

The total bond enthalpy of products of the given reaction is calculated by the relation shown below.

    ΔHB°(products)=(1mol)ΔHB(CH)+(3mol)ΔHB(CCl)+(1mol)ΔHB(CC)+(2mol)ΔHB(CF)+(2mol)ΔHB(HCl)        (2)

Where,

  • ΔHB°(products) is total bond enthalpy of product.
  • ΔHB(CH) is bond enthalpy of CH bond.
  • ΔHB(CCl) is bond enthalpy of CCl bond.
  • ΔHB(CC) is bond enthalpy of CC bond.
  • ΔHB(CF) is bond enthalpy of CF bond.
  • ΔHB(HCl) is bond enthalpy of HCl bond.

The value of ΔHB(CH) is 412kJmol1.

The value of ΔHB(CCl) is 338kJmol1.

The value of ΔHB(CC) is 348kJmol1.

The value of ΔHB(CF) is 484kJmol1.

The value of ΔHB(HCl) is 431kJmol1.

Substitute the value of ΔHB(CH), ΔHB(CCl), ΔHB(CC), ΔHB(CF) and ΔHB(HCl) in equation (2).

  ΔHB°(products)=((1mol)×(412kJmol1)+(3mol)×(338kJmol1)+(1mol)×(348kJmol1)+(2mol)×(484kJmol1)+(2mol)×(431kJmol1))=412kJ+1014kJ+348kJ+968kJ+862kJ=3604kJ

The reaction enthalpy of the given reaction is calculated by the relation shown below.

  ΔHB°=ΔHB°(reactants)ΔHB°(products)        (3)

Where,

  • ΔHB° is reaction enthalpy.
  • ΔHB°(reactants) is total bond enthalpy of reactants.
  • ΔHB°(products) is total bond enthalpy of product.

The value of ΔHB°(reactants) is 3580kJ.

The value of ΔHB°(products) is 3604kJ.

Substitute the value of ΔHB°(reactants) and ΔHB°(products) in equation (3).

    ΔHB°=3580kJ3604kJ=24kJ

The obtained reaction enthalpy of the given reaction is negative, which indicates that the reaction is exothermic in nature.

Thus, the reaction enthalpy for the given reaction is -24kJmol-1_.
