1. A first order reaction has a half-life of 212 seconds. How long will it take for the concentration of the reactant to decrease to 1/16^th of its initial value?
2. The data shown were collected for the following first-order reaction: N₂O(g) N₂(g) + O(g)
3. 1. Use the data to make an Arrhenius plot of lnk vs 1/T. Include the graph when you turn in your homework. (Follow the graphing best practices.)
   2. What is the equation of the line?

      Temperature (K)	Rate constant (1/s)
      800.0	0.0000324
      900.0	0.00214
      1000.0	0.0614
      1100.0	0.955

5. 3. What is the activation energy, in kJ, for the reaction? (calculated from the slope)
