The fuel you burn in your car's engine contains octane, C3H18. When octane is burned, the products are CO2 and H2O. 2C3H18(1) + 2502(g) → 16CO2(g) + 18H20(g) Emissions testing is an important tool for protecting our environment and informs car owners if their car is emitting too much CO2 while driving. Using the balanced equation above, answer the following questions. If 10.22 g of octane (C3H18 ) and 17.35 g of oxygen are used in the reaction, what is the limiting reactant and how much CO2 is produced?
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.
