standard enthalpy of combustion for butan-1-ol is -2685 kJ/mol and is given by the following reaction equation. CHaCH?CH2CH2OH(/) + 6 02(8) - 4 CO2(8) + 5 H20(/) The formation of carbon dioxide and liquid water are given by these equations. C(s) + 02(g) - CO2(g) AH° = -394 kJ/mol H2(g) + 0.5 02(g) - H20(/) AH° = -286 kJ/mol Using these data, determine the standard enthalpy of fbrmation for butan-1-ol. Report your answer in kJ/mol with no decimal place in the answer.
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.
standard enthalpy of combustion for butan-1-ol is -2685 kJ/mol and is given by
the following reaction equation.
CHaCH?CH2CH2OH(/) + 6 02(8) - 4 CO2(8) + 5 H20(/)
The formation of carbon dioxide and liquid water are given by these equations.
C(s) + 02(g) - CO2(g) AH° = -394 kJ/mol
H2(g) + 0.5 02(g) - H20(/) AH° = -286 kJ/mol
Using these data, determine the standard enthalpy of fbrmation for butan-1-ol. Report your answer in kJ/mol with no decimal place in the answer.
