THIS QUESTION IS SOLVED DO THE BELOW ONE(Q10.15): Determine the kinetic energy, in joules per mol (J/mol), of a sample of nitrogen molecules at 100.0 ºC. T= 100C+273=373.2K Ekinetic= 3/2RT= 3/2(8.314mol.K)(373.2K) Ekinetic= 4.6x10^3 J/mol Q10.15:Determine the kinetic energy, in joules (J), of a single gaseous nitrogen molecule at 100.0 ºC. Do not include the unit of measure in your answer. Respond with the correct number of signficant figures in scientific notation. (Use E notation and only 1 digit before decimal, for example, 2.5E5 for 2.5 times 10 to the power of 5)Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimal e.g. 2.5E5 for 2.5 x 10⁵)
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.
