How does the heat produced when 1 mole ofC is burned directly to CO2by the reactionC(s) + O2(g)→CO2(g)compare with that produced when 1 mole ofC undergoes the two-step process:C(s) +12O2(g)→CO(g) morrison (gjm2355) – Chapter 17 – andrews – (7)2CO(g) +12O2(g)→CO2(g)if all reactants and products are at the same temperature and pressure? 1.The heat produced is the same either way. 2.More heat is produced in the two-step process. 3.Cannot tell without calculating the heat produced. 4.More heat is produced in the one-step process.
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.
