Problem 10P

(a) Using bond-dissociation enthalpies from Table 4-2 (page 143), calculate the heat of reaction for each step in the free-radical bromination of methane.

(b) Calculate the overall heat of reaction.

Step-by-Step Solution:
Step 1 of 3

Solution 10P

Given reaction is a substitution; bromine does not add to methane but a bromine atom substitutes for one hydrogen atoms, which becomes part of the HBr byproduct.

Bromination of methane consists of three steps, which are initiation,propagation and termination.

The initiation step, which generates a reactive intermediate:

Light absorbed by bromine, split a bromine molecule into two bromine atoms.

Propagation steps, in which the reactive intermediates reacts with a stable molecule to form another reactive intermediate, allowing the chain to continue until the supply of reactants is exhausted or the reactive intermediate is destroyed.

First propagation step:

Breaking a -Br...
