The energy needed to distort a C-F bond by 0.8 A is 934 kJ/mol. The bond length of this bond is 1.33 A. a) At a temperature of 100°C, the average kinetic energy of the atoms is about: 4.6 kJ/mol Ⓒ460 kJ/mol 4.6 x 10³ kJ/mcl b) How likely is it for such a distortion to occur on this C-F bond at this temperature? Fill in the blanks with one of the choices given. The distortion is likely since the energy needed to distort this bond at this temperature c) How much % of the bond length (/) is this distortion length (-/-)? 60% 0.6% 100% 4.6x10³ kJ/mol much higher than the RT value. 6%
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.
