Question

1. A student mixed the following reactants, using the general procedure for the experiment: 13.98 mL of 0.1000M KI, 19.76 mL of 0.001000 M Na2SO3, 11.42 mL of 0.04000M KBrO3, and 14.33 mL of 0.1000M HCl. It took about 75 seconds for the mixture to turn blue. Calculate the concentration of H+ in the mixture after all of the solutions have been combined

2. A student collected conducted 6 kinetics experiments for one reaction by holding the concentrations of ALL the reactants and catalyst constant and varying the temperature. After determining the rate constant  for this reaction at the 6different temperatures, an Arrhenius Plot was made. The graph resulted in a straight line. The equation for the straight line was: y= -3,696.41 x + 14.326

What is the Activation Energy for this reaction at 30 ^oC?
