makes sense because there would be less reactants than there were initially, so less molecules would make it over the activation barrier. E. Reflection (Any necessary calculations should be clearly shown or attached.) 1. (a) Assume that the reaction order for hydroxide ion is 1 st order. Write the rate law for the reaction at each temperature that you used; include the numerical value for the rate constant. At 23.4 °C: ¿ O H ¿ rate = 0.0012 [ CV ] ¿ At 3.4 °C: ¿ O H ¿ rate = 0.0002 [ CV ] ¿ (b) Using this rate law and the concentrations from the experiment, calculate the rate of reaction for each temperature that you measured. At 23.4 °C: rate = 0.0012 ( 2.0 10 5 ) ( 0.020 ) = 4.8 10 10 M s 1 At 3.4 °C: rate = 0.0002 ( 2.0 10 5 ) ( 0.020 ) = 8.0 10 11 M s 1
2. (a) According to your data and results, what is the correlation between the change in temperature and the change in rate? When the temperature decreased the rate decreased. Therefore there is a direct correlation between change in temperature and change in rate. (b) Knowing what is required for a reaction to occur (see introduction above), explain why temperature affects the rates of reactions. When looking at the Arrhenius equation, k = A e E a RT , you can see that temperature is in the denominator of the exponent. This means that as the temperature increases
