T (K) k (s -1 ) 273 9.89x10 3 298 2.20x10 5 318 6.58x10 6 338 3.98x10 7 Determine graphically the activation energy (Ea) for the reaction. Practice with Half life A solution that is 5.2x10-8 M in 32P is stored in a metal container for 100 days. 1. Plot the decay in the concentration of 32P as a function of time. The half life of 32P is 14.3 days. 2. Plot ln[32P] as a function of time. 3. Show on both plots when the [32P] is 50%, 75% and 90% of its original value. 4. Show how you could use the plot of the natural log to obtain the rate constant and
