In this lesson, you learned about factors that can influence reaction rates, as well as how concentration and reaction rate are related. To show what you learned in this lesson, complete the mathematical problems below.

Make sure to show your work

• The rate law for a reaction is found to be rate = k[X]4. By what factor does the rate increase if [X] is doubled?
• The rate of a hypothetical reaction involving L and M is found to triple when the concentration of L is doubled and to double when the concentration of M is doubled. Write the rate law for this reaction.
