Given the unbalanced reaction: MnO4 (aq) + Br (aq) + H* (aq) + H,O ()= Mn2 (ag) + Br2 (1) + H2O (1) + H* (ag) (The reaction is in an acid solution and not balanced) What are the coefficient of the balanced over all chemical reaction? Input only the number values of the cocfficient for each substance in the reaction. Note I have put both water and hydrogen ions on both sides of the reaction. If they are not needed to balance the reaction, place a zero as its coefficient. You can not leave a box blank, it will be counted as incorrect. G The reaction of C6H1206(s) 6
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.
