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.
How do you find the heat released per mol of reactant using this data found?
![**The Heat of Neutralization of Hydrochloric Acid and Sodium Hydroxide**
- **Mass of empty, dry calorimeter:** 187.15 g
- **Mass of calorimeter and acid:** 258.52 g (subtract to find mass of acid)
- **Mass of calorimeter, acid, and base:** 333.29 g (subtract to find mass of base)
- **Initial temperature of solutions \(T_i\):** 21.1°C
- **Final temperature after reaction \(T_f\):** 30.5°C
**Calculations:**
[Space for detailed calculations based on the above data]
**Results:**
- **Heat released per mol reacted:** \( \text{J/mole} \) [Space for final result]
The experiment involves measuring the heat of neutralization when hydrochloric acid reacts with sodium hydroxide, using the calorimeter to track temperature changes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F32e33d2f-c157-43e7-b72d-4853ffe1c76c%2F361065bb-542f-4072-9819-410b7b999999%2Fu1krjte_processed.jpeg&w=3840&q=75)
