Constants | Periodic Table
Calorimetry is a method used to measure enthalpy.
or heat, changes that occur during chemical
processes. Two common calorimeters are
constant-pressure calorimeters and constant-
volume (or "bomb") calorimeters.
Part A
A simple constant-pressure calorimeter can be
made from a foam coffee cup and a thermometer;
energy changes in a reaction are observed via a
temperature change of the solution in the cup.
Bomb calorimeters are used to
combustion and other gas-producing reactions,
where the reaction is observed in
vessel. The idea behind calorimeters is that if they
are sufficiently insulated from the outside
environment, any energy gained or lost in the
chemical reaction will be directly observable as a
temperature and/or pressure change in the
calorimeter.
A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction
produces 107 g of solution. The reaction caused the temperature of the solution to rise from 21.00 to 24,70
C. What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup
itself and that the specific heat of the solution is the same as that of pure water.
