in rate is only due to the change in concentration of A (Propanone). The concentration of propanone in experiment 2 is the double of it in experiment 1. Something similar happens with the rate: In experiment 2 the rate is almost the double than the rate of experiment 1. This means that the order of [C3H6O] is 1. 2) In experiment 4 and 5 [Solution B] is the only one which changes. The concentration of iodine in experiment 5 is the half than in experiment 4. It is noticeable that the rate didn’t

of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant to use the same timer in recording the time of reaction because

to compare the two reactors used in our experiment‚ a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15‚ 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21‚ 24-25]. The chemical kinetics model was based on the following step process: The reactant molecules CH4 or

on the reaction rate of enzyme and substrate. Results indicated that the enzyme functions efficiently at its optimum temperature (50oC) digesting the starch present and that any sign of enzyme function at 70oC is completely nonexistent. In summary the experiments conducted in the EEI succeeded in demonstrating the effects temperature has enzyme activity and just how vital enzymes are for biological life. INTRODUCTION: Enzymes are biological catalysts. They speed up chemical reactions in all
