Concept explainers

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.

Question 11 X Incorrect. Isooctane, C3H18, is the basis of the octane rating system for gasoline because it burns smoothly, with minimal engine knocking. Pure isooctane is assigned a value of 100. Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane. Please note the combustion is exothermic process and the released energy is positive for the surroundings. -285.8 kJ
