plz help with 4&5

4. A well-known approximation in chemistry states that the rate of a reaction often doubles for every 10C increase in temperature. Use your data to test this rule. (Note: It is not necessarily equal to 2.00; this is just an approximate value, and depends on the activation energy for the reaction.) 5. Using the rate constant and precise temperature value for the trial that was done at room temperature ( 20C), as well as the Ea value you obtained in Step 3 above, calculate the vaiue of the rate constant at 40C. lnK2K1REa(T21T11)
