Lab 3 Reaction Rates Report

Answer 1 and 2. Show complete solution.

Sample Designs: Test one group against another group of experiment on the same reaction time test Compare the reaction times of the same people under two different conditions, like after exercise A test subject attempts to grab the ruler as it is dropped, the number on the ruler where the fingers grasp it can be used to judge reaction time Digital reaction time tests are easy to find with a google search You can also install an app on your phone that can measure reaction time (useful if you want to test subjects outside of class) C) How will you gather data? Will you take averages?

Plot a Graph and Determine the Rate: Make a graphical plot of reaction time (× axis) and average (y axis). Determine the initial velocity (rate of the reaction by extending the initial straight-line portion of your reaction curve and calculating the gradient of the straight line (difference in y/ difference in ×).  What is the reaction rate based on your plotted values

Directions: Write the letter of the word or phrase that best completes the statement or answers the question on the space provided. I. first order J. reaction order A. catalysts E. temperature F. rate of reaction G. reactivity B. concentration C. rate law D. surface area H. reactants 1. It refers to the amount of substance per unit volume. 2. Some reactions are slow and some are fast. 3. It tells the concentration dependence of one reactant in a reaction. 4. It is characterized as the tendency of a material to undergo a chemical reaction. 5. It shows the relationship between concentrations of reactants and reaction rate. 6. It describes the powers of the concentration factors in the rate equation. 7. It is a property of a material which increases as particle size decreases. 8. These are substances that go away with time in a reaction. 9. It increases the kinetic energy present in a material. 10. These are materials that do not change their amount throughout the chemical reaction.

Plot each point from the table on to a graph. Label the x/y axis and title. DON'T connect the points.  Only draw one line, which is that straight line. Instructions in photo.

Write the balanced reaction that corresponds to the data in graph.

Question 1 of 10 >>>> 1 points Save Answer In general, reaction rates double when the temperature is increased by 10° C. The temperature of a reaction is increased by 30° C. The rate of the reaction will increase by a factor of: A Moving to another question will save this response. Question 1 of 10 >>>> K

Some measurements of the initial rate of a certain reaction are given in the table below. Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol.

The attached image shows the different amounts and concentrations for an iodide clock experiment, showing the effects of persulfate and iodide concentrations on reaction rate. How do I fill up this table? Please provide a general formula/solution for solving for the Molarity portion. Runs [S2O8 2-], M [I–], M [S2O3 2-], M Reaction time,s Rate, M/s 1       49.10   2a       106.10   3       197.44   4       69.20   5       53.05

The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product.    Using the internet , research the one factors below that affect the rate of a chemical reaction.    1. Reactant concentration  ( add an example and be very detailed add graphs as well)   Be sure to include the following terms as they relate to chemical reactions: collision theory  Be very detailed potential energy diagrams   be very detailed activation energy  be very detailed Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!

4. A. B. C. D. E. 5. A. Which one of the following statements is correct? A catalyst that is present in the same phase as the reacting molecules is a heterogeneous catalyst. Elementary steps involving the simultaneous collision of two molecules are bimolecular. Absorption refers to the binding of molecules to a surface. Because the fast step limits the overall reaction rate, it is called the rate- determining step. A balanced chemical reaction equation details the individual steps that occur in the course of a reaction. A reaction NO₂(g) + CO(g) → NO(g) + CO₂(g) obeys the following rate law: Rate = K[NO₂]². What are the units for the rate constant? M¹.S¹
