I figured out the first three questions but am stuck on the last one In the upper atmosphere, ozone is produced from oxygen gas in the following reaction. 3O2(g) → 2O3(g) Calculate ΔHo for this reaction. Enter your answer in kJ and give 3 significant figures. 285 You are correct.Your receipt no. is 155-2894 Previous Tries Calculate ΔSo for ozone formation. (Enter your answer in J/K and give 3 significant figures). -141 You are correct.Your receipt no. is 155-2957 Previous Tries Calculate ΔGo for ozone formation. (Enter your answer in kJ and give 3 significant figures). 326 You are correct.Your receipt no. is 155-1799 Previous Tries Assume an atmosphere where p(O2) = 0.200 atm, and where T = 298 K. Below what pressure of O3 will ozone production be spontaneous? (Enter your answer in atm).
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.
