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…

Textbook Question

Chapter 8, Problem 105QGW

Consider the combustion of propane:

C 3 H 8 ( g ) + O 2 ( g ) → C O 2 ( g ) + H 2 O( g )

a. Balance the reaction.

b. Divide all coefficients by the coefficient on propane, so that you have the reaction for the combustion of 1 mol of propane.

c. ∆H_rxn for the combustion of one mole of propane is −2219 kJ. What mass of propane would you need to burn to generate 5. 0MJ of heat?

d. If propane costs about $0.67/L and has a density of 2.01 g/cm³, how much would it cost to generate 5.0 MJ of heat by burning propane?
