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.
![**Chemical Reaction Yield Calculation Practice**
In this exercise, you'll learn how to calculate the necessary amount of a reactant based on percent yield.
**Problem Statement:**
If the percent yield of the reaction below is 78%, how many grams of chlorine gas are needed to produce 315.0 g of phosphorus trichloride (PCl₃)? Show all your calculations on a separate piece of paper and submit them as part B. Clearly label the question number and answer. Failure to demonstrate your work will result in a score of zero for this question.
**Chemical Reaction:**
\[ P_4(s) + 6Cl_2(g) \rightarrow 4PCl_3(l) \]
**Instructions:**
- Use the provided chemical equation to solve the problem.
- Calculate the theoretical yield and then determine the required amount of chlorine gas considering the 78% yield.
- Be sure to include all steps and calculations in your work.
**Submission:**
Type your answer in the space provided below. Show all calculations on a separate sheet.
