Detailed Lesson Plan (DLP)

This document provides a detailed lesson plan for an 11th grade physical science class on calculating percent yield in chemical reactions. The lesson plan aims to teach students to calculate the theoretical and actual yield of a reaction and determine percent yield. It includes objectives, content, resources, procedures such as introductory activities, sample problems, analysis, lecture, application problems and assessment. The procedures take students through identifying theoretical yield, relating it to a real-world example, calculating theoretical yield in a sample reaction, understanding the concepts of theoretical versus actual yield, and practicing calculation of percent yield in example problems.

4. PROCEDURES
4.1 Introductory Activity 1. The teacher introduces the learning objectives.
2. Imagine that you can have 100 chances to shoot a ball inside the ring. Theoretically, you can make all the 100 shots. However,
in actuality, you may not make all them. There would be a difference between your theoretical and actual outcomes.
3. The teacher relates this to chemical reactions. How can you express the difference between theoretical and actual product
yields?
4.2 Activity Tell students that in the previous lesson they calculated the amount of product formed in a chemical reaction. This amount of
product is the theoretical yield in a chemical reaction.
Ask students to find a pair from their seatmate. Then, they are to answer the following activity.

Consider the reaction below:


2NaOH + H2SO4→ Na2SO4 + 2H2O
What is the theoretical yield (in grams) of Na2SO4that will be formed when 4 moles of NaOH is used in the reaction?
4.3 Analysis 1. How did you find the activity?
2. What do you understand about theoretical yield? How about actual yield?
3. Can you identify the theoretical and actual yield in the given reaction?
4. How can you express the difference between theoretical and actual product yields?
(Solicit varied answers from the students.)
4.4 Abstraction Lecture-Discussion of Key Concepts:
The theoretical yield is the maximum amount of product that can be formed by a chemical reaction from the given amount of
reactant.
The actual yield, also called the experimental yield, is the real amount of product formed from the reaction when the
experiment is performed.
The ratio of actual yield to theoretical yield multiplied by 100 is the percent yield (% yield).
Chemical reactions do not always go into completion (not 100% successful). Therefore, percent yields are usually less than
100%.
4.5 Application Suppose you use 40g NaOH and produced 15g H2O. What is the percent yield of H2O?

4.6 Assessment Consider the synthesis of NaCl from Na and Cl2. The reaction is represented by the balanced chemical equation below.
2Na + Cl2 →2NaCl
When 10g of Cl2is used, the reaction produced 12.5g NaCl. What is the percent yield of the reaction?
4.7 Assignment What is the difference between limiting reactant and excess reactant?
4.8 Concluding Activity
