Please provide these answers 25. For an isochoric process, the thermal effect is equal to: changes in Gibbs free energy. changes in entropy of the system. enthalpy change of the process zero changes in internal energy. 26. System state functions depend on: the ability of the system to return to its initial state values of the chemical equilibrium constant exchange of matter and energy with the environment initial and final state of the system way of complying with the process 27. Heat and work depend on: exchange of matter and energy with the environment initial and final state of the system the ability of the system to return to its initial state values of the chemical equilibrium constant way of complying with the 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.
