Open up your spreadsheet program and use the data provided to plot a graph of lntd versus 1/T. Find the equation of your best fit line. From your graph determine the activation energy of the reaction (kJmol1 to two significant figures and the Arrhenius constant, A to one significant figure. The activation for the reaction in kJmol1 (two significant figures) is Answer The Arrhenius constant A (one significant figure) is Answer: A solution containing 4cm3 of 0.05MNa2S2O8(aq) and 6cm3 of water in one test tube is mixed with 10cm3 of 0.04MKI(aq),1cm3 of 0.001MNa2S2O3(aq) and 1cm3 of starch in another test tube and the time it takes to change color is measured. The concentration of S2O82 (aq) (M) (two significant figures) at the instant of mixing is Answer: The concentration of I(aq) (M) (two significant figures) at the instant of mixing is Answer: The concentration of S2O32(aq)(M) (two significant figures) at the instant of mixing is Answet
