After you calculate a value for y (on Data Sheet 2) and using your average x (on Data Sheet 1), calculate the rate constants for each of determinations 1-4. Remember to round x and y to integers. Determination Determination Determination Determination 2 3 Rate constant, k Using your average x (from Data Sheet 1) and y (from Data Sheet 2), calculate the rate constants for each of determinations 5-8. Remember to round x and y to integers. Determination Determination Determination Determination 5 6 7 8 Rate constant, k Rate law: rate= Additional Questions 1. The rate is dependent on temperature. What kind of temperatures were used to study the effect of temperature on the reaction rate in the Video? Convert the Kelvin to °C. 2. What did they put the beaker holding the reaction mixture into to perform the low temperature and the high temperature determinations? 3. What can you tell about the effect of temperature on the reaction rate at high temperature and at low temperature based what you saw in the Video? 4. Write down the Arrhenius equation and the linear form of the Arrhenius equation. What value was calculated in the Video by using them?
