Answer to Problem 4E.5E

The reaction enthalpy for the given reaction is -597 kJmol-1.

Explanation of Solution

The given reaction is,

  3C2H2(g)C6H6(g)

In the reactant side, the bond enthalpy of C2H2 is calculated as,

The bond enthalpy of C-H bond is 412kJmol-1.

  2×412kJmol-1=824kJmol-1

The bond enthalpy of CC is 837kJmol-1.

  1×837 kJ×mol-1=837 kJmol-1

The total bond enthalpy is 3(837kJmol-1+824kJmol-1)=4983kJmol-1

The total bond enthalpy in reactant side is 4983kJmol-1.

In the product side, the bond enthalpy of C6H6 is calculated as,

The bond enthalpy of C=C bond is 518kJmol-1.

  6×518kJmol-1=3108kJmol-1

The bond enthalpy of C-H bond is 412kJmol-1.

  6×412kJmol-1=2472kJmol-1

The total bond enthalpy is (3108 kJmol-1+2472kJmol-1)=5580kJmol-1

The total bond enthalpy in product side is -5580kJmol-1.

Negative sign indicates the bonds are broken.

The reactant enthalpy is,

  ΔHo=4983kJmol-1+(-5580kJmol-1)ΔHo=-597kJmol-1

Answer to Problem 4E.5E

The reaction enthalpy for the given reaction is -460kJmol-1.

Explanation of Solution

The given reaction is,

  CH4(g)+4Cl2(g)CCl4(g)+4HCl(g)

In the reactant side,

The bond enthalpy of C-H bond is 412kJmol-1.

  4×412kJmol-1=1648 kJmol-1

The bond enthalpy of Cl2 bond is 242kJmol-1.

  4×242kJmol-1=968 kJmol-1

The total bond enthalpy is (1648kJmol-1+968kJmol-1)=2616kJmol-1

The total bond enthalpy in the reactant side is 2616kJmol-1.

In the product side,

The bond enthalpy of C-Cl bond is 338kJmol-1.

  4×338kJmol-1=1352 kJmol-1

The bond enthalpy of HCl bond is 431kJmol-1.

  4×431kJmol-1=1724kJmol-1

The total bond enthalpy is (1352kJmol-1+1724kJmol-1)=3076kJmol-1

The total bond enthalpy in the product side is -3076kJmol-1.

Negative sign indicates the bonds are broken.

The reactant enthalpy is,

  ΔHo=2616kJmol-1+(-3076kJmol-1)ΔHo=-460kJmol-1

The reaction enthalpy for the given reaction is -460kJmol-1.

Answer to Problem 4E.5E

The reaction enthalpy for the given reaction is 0kJmol-1.

Explanation of Solution

The given reaction is,

  CH4(g)+CCl4(g)CHCl3(g)+CH3Cl(g)

In the reactant side,

The bond enthalpy of CH4 is calculated as,

The bond enthalpy of C-H bond is 412kJmol-1.

  4×412kJmol-1=1648 kJmol-1

The bond enthalpy of CCl4 is calculated as,

The bond enthalpy of C-Cl bond is 338kJmol-1.

  4×338kJmol-1=1352 kJmol-1

The total bond enthalpy is (1648kJmol-1+1352kJmol-1)=3000kJmol-1

The total bond enthalpy in the reactant side is 3000kJmol-1.

In the product side,

The bond enthalpy of CHCl3 is calculated as,

The bond enthalpy of C-H bond is 412kJmol-1.

  1×412kJmol-1=412 kJmol-1

The bond enthalpy of C-Cl bond is 338kJmol-1.

  3×338kJmol-1=1014 kJmol-1

The bond enthalpy of CH3Cl is calculated as,

The bond enthalpy of C-H bond is 412kJmol-1.

  3×412kJmol-1=1236 kJmol-1

The bond enthalpy of C-Cl bond is 338kJmol-1.

  1×338kJmol-1=338 kJmol-1

The total bond enthalpy is

(1014kJmol-1+412kJmol-1+1236kJmol-1+338kJmol-1)=3000kJmol-1

The total bond enthalpy in the product side is -3000kJmol-1.

Negative sign indicates the bonds are broken.

The reactant enthalpy is,

  ΔHo=300kJmol-1+(-3000kJmol-1)ΔHo=0kJmol-1

The reaction enthalpy for the given reaction is 0kJmol-1.
