Based from the given picture, a family chose to drive going to school instead to walk. The car, being the catalyst in the said situation. For now, in order to reveal our new lesson, we will play a game called “Name it to Win it!”. I will call a student to guess the word or phrase in the box. You’ll just need to tell me the letters of the word. Each word has something to do with our topic today. Are you ready? Let’s proceed then. INDICATOR4. Used effective verbal and nonverbal classroom communication strategies to support learner understanding, participation, engagement and achievement. 1.In this part of the lesson, the teacher will provide positive feedback to the learner’s response. Analyze the given picture then answer the following question. What can you say about the pictures shown? Compare each pair and tell which one is more spontaneous than the other? INDICATOR 4.

Applied a personal philosophy of teaching that is learner-centered. H. Making generalizations and abstractions about the lesson I. Evaluating learning What general rules apply to predicting whether an entropy change is negative or positive? Possible Answer: 1. If the reaction produces more gas molecules than it consumes, ΔS° is positive. 2. If the total number of gas molecules diminishes, ΔS° is negative. 3. If there is no net change in the total number of gas molecules, ΔS° may be positive or negative, but will be relatively small numerically. Assessment Directions: Write the letter of the best answer on your answer sheet. SHOW YOUR SOLUTIONS! 1. What is the entropy change of the reaction below at 298 K and 1 atm pressure?
