You are interested in determining the heat of isomerization of
two isomers (A and B), so you measure their heats of combustion.
The difference between the heats of combustion is equal to the heat
of isomerization. You are given two separate samples of (1.5 ± 0.1)
mol for each isomer, A and B, and they are burned in a
constant-pressure calorimeter.
The heat of capacity of the calorimeter is (8.44 ± 0.05) kJ K-1.
Combustion of isomer A causes the...
