The design of air-bag depends on stoichiometric precision. The following reaction takes place when the air-bag is inflated. 2 NaN3 (s) → 2 Na(s) + 3 N2 (g) 6Na(s) + Fe2O3(s) → 3NA2O(s) + 2Fe Assume that 43.4 L of nitrogen gas are needed to inflate an air bag to the proper size. (A) How many grams of NaN3 must be included in the air-bag to generate this amount of nitrogen gas? (The density of nitrogen gas at this temperature is 0.916 g/L). (B) How much Fe2 O3 (in grams) must be added to the air-bag for this amount of NaN3?
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.
