Chemistry Unit 3 Day 2

Learning Objective: Students will learn about spontaneous chemical reactions using an inquiry simulation and will analyze and interpret data in writing using technical vocabulary (entropy, enthalpy, energy diagram, reactants, products, activation energy).

 Questions:

  1. What makes a chemical reaction spontaneous? (book)
  2. Would a spontaneous reaction happen faster or slower? why do you think? (brain)
  3. What does the entropy of a reaction describe?
Answer Choices for number 3:
  • A. The amount of heat present in the system
  • B. The amount of randomness in the system
  • C. The amount of usable energy in a reaction
  • D. The number of molecules in a system
Exit Ticket for Day 2: 
  • Suppose you had to explain spontaneous reactions to a friend, how would you explain it? (2-3 sentences)
  • What would be the most difficult part for you to explain?
