2 Chemistry 12: First Assignment You need the reading booklet in order to complete all parts of this assignment. It should be downloaded from this link: First Assignment has 2 Parts: Part A: Unit 1 Lesson 1 - Reaction Rate Defined and Factors Affecting Reaction Rate {Part 1 & Part 2} (There are 2 quizzes that need to be done here. Part 1 which has four true and false questions and part 2 that has ten multiple choice questions. The reading material for these questions are in the reading booklet which needs to be downloaded from the above link) Unit 1 Lesson 2 Collision Theory (Here you just have one multiple choice question to complete that is worth 2 marks) Part B: Practice Work Questions Exercises #1 22 & Answer key. Please hand write answers to these questions ***showing all your work step by step.*** This first assignment is worth 5% of your total grade You can use calculators and Chemistry 12 Formula sheets throughout this course The course demonstrates the following Learning Standards following the completion of this First Assignment: Dynamic Equilibrium Some chemical reactions are reversible and proceed to equilibrium. Dynamic equilibrium can be altered by changing the surrounding conditions. Solubility Equilibrium Saturated solutions are systems in equilibrium. Acids and Bases The strength of an acid or base depends on the degree of dissociation of its ions. Weak acids, weak bases, and buffers are systems in equilibrium.

3 Oxidation-Reduction Reduction and oxidation are complementary processes that involve the gain or loss of electrons. Redox reactions have implications for resource development and for the environment. Unit 1 Lesson 1 - Reaction Rate Defined and Factors Affecting Reaction Rate Please read Pages 2-6 in the reading booklet and then come back here to complete Unit 1 Lesson 1; Part 1 and Part 2 quiz questions Unit 1 Lesson 1 Quiz Part 1 - Instructions - This is an Open Book Quiz. Put a check mark next to the correct answer for each of the following four questions, either True or False. ( / 4 marks total) 1. (1 mark) Reaction rate = the rate of appearance of a product or the rate of disappearance of a reactant True False 2. (1 mark) The following are four of the factors which affect reaction rate: Catalysts, Concentration, Nature of reactants and Temperature True False 3. (1 mark) Homogeneous Reaction = All the reactants are in different phases/states True False 4. (1 mark) Surface area is only important in heterogeneous reactions True False Total = / 4 marks

8 Please read Pages 7-8 in the reading booklet and then come back here to complete Unit 1 Lesson 2 quiz question Unit 1 Lesson 2 - Collision Theory 3.0 Collision Theory For a reaction to occur, reactant particles must collide, creating an opportunity for old bonds to break and new bonds to form. Any one collision may be successful or unsuccessful depending on two factors. Read more on the reading booklet Unit 1 Lesson 2 Quiz - Instructions - This is an Open Book Quiz.
