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 …

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 energ…

Chapter 5, Problem 121AP

A gas company in Massachusetts charges 27 cents for a mole of natural gas ( CH 4 ) . Calculate the cost of heating 200 mL of water (enough to make a cup of coffee or tea from 20°C to 100 ° C . Assume that only 50 percent of the heat generated by the combustion is used the water: the rest of the is lost to the surroundings.
