06/ For the following reaction: CH4(g)+202(g) CO₂(g)+2H₂O(1) 10 moles of CH4 reacted with 25 moles of O₂ and 10 moles of CO₂ formed. Given, the enthalpies of formation of CH4, CO₂ and H₂O are 74.8 kJmol, -393,5 kJmol, -286 kJmol respectively. The feed enters at 298 K. Use the following data to estimate the temperature of the products.
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.
