2. A 48.33-mL sample of 0.150 M NaBr is titrated into 50.00 mL of 0.145 M AgNO3. Both solutions had the same initial and final temperatures. The reaction occurred in a calorimeter with a known heat capacity and produced 1546.03 J of heat. i. Write a balanced equation that is occurring. ii. Determine the theoretical yield of the solid. iii. Calculate the enthalpy of the reaction (kJ/mole of precipitate).
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

![Section ll: Practice Problems
1. When you arrive at the lab, 2.0 M H2SO4(aq) and 2.0 M HC2H3O2(aq) Will be present. You
will need to dilute these solutions using beakers and graduated cylinders from your drawer
and DI water.
i. Calculate the volume of the 2.0 M HC2H3O2(aq) and DI water needed to create 50.0 mL
of 1.05 M HC2H3O2(aq).
ii. Calculate the volume of the 2.0 M H2SO4(ag) and DI water needed to create 50.0 mL of
0.75 M H2SO4(aq).
