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.
Question
Transcribed Image Text:The image is a chemistry problem related to percent yield. It presents the following text:
---
"The percent yield for the reaction is 87.2%. How many grams of the precipitate are formed?"
There is a text box for input labeled "precipitate formed:" with units in grams (g), followed by a label stating "Incorrect."
---
"Taking into account the percent yield, how many grams of the excess reactant (the reactant that is not limiting) remain?"
Another text box for input is labeled "excess reactant remaining:" with units in grams (g), also followed by a label stating "Incorrect."
---
There are no graphs or diagrams in the image.
![### Chemical Reaction Example
**Scenario:**
An aqueous solution containing 9.83 g of lead(II) nitrate is added to an aqueous solution containing 6.94 g of potassium chloride.
**Task:**
Enter the balanced chemical equation for this reaction. Be sure to include all physical states.
**Balanced Chemical Equation:**
\[ \text{Pb(NO}_3\text{)}_2\text{(aq) + 2KCl(aq) → PbCl}_2\text{(s) + 2KNO}_3\text{(aq)} \]
**Question:**
What is the limiting reactant?
- ○ potassium chloride
- ● lead(II) nitrate (selected)
**Explanation:**
This example illustrates a typical chemical reaction between lead(II) nitrate and potassium chloride. The reaction forms lead(II) chloride as a solid precipitate and potassium nitrate remains in aqueous solution. Determining the limiting reactant is essential to find out which reactant will be completely consumed first, stopping the reaction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcf156db5-b410-4456-9ca9-cc28e5516dc6%2F939de33e-cacf-4e28-b9aa-bf6c38fafe79%2F8ybo11_processed.jpeg&w=3840&q=75)
