Calculate the work, w, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 18.0 L. Paraphrasing lool... Check Answer Question Source: McQuarrie, Rock, And Gallogly de-General Chemistry Now calculate the work done if this process is carried out in two steps. 1. First, let the gas expand against a constant external pressure of 1.80 atm to a volume of 10.0 L. 2. From the end point of step 1, let the gas expand to 18.0 L against a constant external pressure of 1.00 atm. Attempt 2 Publisher: University Science Books 9:34 AM 11/18/2022 □
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.
