Ch 14: Errors in Publisher's Solution Manual - 11th edition

[Zellmer, Robert]

The publisher's solution to 14.88 in the 11th edition is wrong.
The problem gives information about how the half-life changes
as the reaction proceeds for two different reactions.  It then asks
what can you conclude about the rate laws of the two reactions
(i.e. are the zero, first or second order).

The solutions manual for the 11th edition erroneously states the
half-lifes for both reactions are constant over the course of the
reaction.

This is incorrect.  The only rate law for which the half-life is constant
and doesn't depend on conc. is first order.  The half-life for all other
orders depends on conc. and thus changes as the reaction proceeds.

This is 14.102 in the 12th ed. and 14.96 in the 13th & 14th eds.  The
solution in the solutions manuals for these editions is correct.
