Selenium tetrafluoride is produced from a reaction of elemental Se with chlorine trifluoride according to the balanced chemical equation: 3 Se(g) + 4 CIF3(g) → 3 SeF4(g) + 2 Cl2(g) AHrxn = -1874 kJ Using AHrxn and the table of bond energies below, determine the bond energy of the Se-F bonds in SeF4. Note that all bonds in the reactants and products are single bonds. Bond Bond Energy (kJ/mol) CI-F 253 Cl-CI 243 The units are kJ/mol. Do not include units in your answer. Scientific notation is optional. To write scientific notation in Canvas, type "e" to replace “x 10". For example, “1 × 1014" is written “1e+14" in Canvas.
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.
Please answer question 2
![**Selenium tetrafluoride is produced from a reaction of elemental Se with chlorine trifluoride according to the balanced chemical equation:**
\[ \text{3 Se}(\text{g}) + \text{4 ClF}_3(\text{g}) \rightarrow \text{3 SeF}_4(\text{g}) + 2 \text{Cl}_2(\text{g}) \quad \Delta \text{Hrxn} = -1874 \, \text{kJ} \]
**Using \(\Delta \text{Hrxn}\) and the table of bond energies below, determine the bond energy of the Se-F bonds in SeF\(_4\).**
*Note that all bonds in the reactants and products are single bonds.*
| Bond | Bond Energy (kJ/mol) |
|-------|----------------------|
| Cl-F | 253 |
| Cl-Cl | 243 |
*The units are kJ/mol. Do not include units in your answer. Scientific notation is optional. To write scientific notation in Canvas, type “e” to replace “× 10”.
