estion 4: Fill in the blanks with the suitable concept: The process due to which chemical changes take place by passing ectric current from an external source. : Is a stream of charged particles, such as electrons or ions, moving (2) through an electrical conductor. : The current through a conductor between two points is (3) directly proportional to the voltage across the two points. : The conductance of all ions produced by dissolving 1 mole of an must be applied to a solution to stop the flow of
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.
