What is the equation that relates rate, change in concentration and time. correct answers Rate = change in concentration ÷ time. How to find the units of the rate constant? correct answers 1. Rearrange the equation to make k the subject. 2. Substitute units into the expression of k 3. Cancel common units and show the final units on a single line. What is the definition of half life? Which order has a constant half life? correct answers Half life: is the time taken for half of a reactan...

AP CHEM FINAL EXAM | Complete Updated Answered Solution guide 2023. 6.1 For a classroom demonstration, a chemistry teacher puts samples of two different pure solid powders in a beaker. The teacher places the beaker on a small wooden board with a wet surface, then stirs the contents of the beaker. After a short time the students observe that the bottom of the beaker is frozen to the wood surface. The teacher asks the students to make a claim about the observation and to justify their claims. W...

Chemistry 18 - Kinetics 2 Questions & Answers What are the main factors that affect reaction rate? Temperature, concentration (solutions), pressure (gases), surface area (solids), catalysts. What is the rate of reaction? The change in concentration of any of the reactants or products with unit time. Usually it is assumed that a rate is measured by following the concentration of a product, because the concentration of the product increases with time. Previous Play Next Re...
