Explanation Given: Solid carbon-C(s, graphite), gaseous hydrogen- H 2 (g), and sugar glucose- C 6 H 12 O 6 (s) are all burned with oxygen in a bomb calorimeter, and the amount of heat given off is determined for each process. The chemical reactions of combustion of Solid carbon-C(s, graphite), gaseous hydrogen- H 2 (g), and sugar glucose- C 6 H 12 O 6 (s) with oxygen in bomb calorimeter are (respectively): C s + O 2 g → ∆ CO 2 g ΔH rxn = ΔH c H 2 g + 1 2 O 2 g → ∆ H 2 O g ΔH rxn = ΔH H 2 C 6 H 12 O 6 s + 6 O 2 g → ∆ 6 CO 2 g + 6 H 2 O g ΔH rxn = ΔH sugar ΔH c , ΔH H 2 , and ΔH sugar are the amounts of heat determined from the calorimeter for each of the processes respectively. From above equations, we can see that ΔH c is the heat of formation of 1 mole of CO 2 (g) from solid carbon and ΔH H 2 is the heat of formation of 1 mole of water (vapor) from hydrogen gas...

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 …

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…
