 In order to determine the dependence of the reaction rate on  temperature and concentration of a peroxydisulfate ion and iodide ion reaction, several  trials were conducted with varying concentrations and a different temperature.  The data  collected was used to calculate the order of the reaction, the rate constant, the rate of  the reaction, and the activation energy.  The data is displayed in Table 1.  Table 1: Data Sample  Trial Vol. S 2 O 8 2- (mL) Concentration  (M) Vol. KI (mL) Concentration  (M) Time (s)  Rate (M/s) 1 1 20 0.029 20 0.039 19.7 2.79 x10 -7 (31 oC ) 2 20 0.029 20 0.039 18.3 3.01x10 -7 3 20 0.029 20 0.039 18.3 3.01x10 -7 2 1 40 0.058 20 0.039 9.5 1.15x10 -6 (31  oC ) 2 40 0.058 20 0.039 8.8 1.25x10 -6 3 40 0.058 20 0.039 8.9 1.24x10 -6 3 1 20 0.029 10 0.019 40.0 1.37x10 -7 (31  oC ) 2 20 0.029 10 0.019 42.3 1.30x10 -7 3 20 0.029 10
