The leachate pond consists of Compound I at a concentration of 3.5 x 10-4 M. If the combustion reaction in d(i) releases -1215kJ, calculate the temperature change of the pond assuming that the pond has a volume of 15000L, density of 1080g/L and its specific heat is the same as pure water.
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.
Landfills usually contain a large deposit of various organic material that degrade over time producing a plethora of secondary pollutants. These compounds are displaced by the action of leachate and eventual accumulate in the leachate pond.
One such organic molecule is compound I drawn below:
