show an example calculation each for how you determined the initial concentration of KIO3 and H2SO Part III: Rate of Reaction at Different Temperatures Temperature °C Time required Mixture1 Trial 1 oC Trial 2 CALCULATIONS Show an example calculation each for how you determined the initial concentration of KIO, and Use graphical analysis as your instructor directs to determine the order of [KIO,] and [H,SO,] in this reaction. When you determine the order, you will also calculate the specific rate constant, k, relative to each. To do this you will plot the three different treatments of the concentration versus time. Create the graphs listed below and attach them to your lab report 1. Plot of initial concentration [KIO,] versus time. 2. Plot of In[KIO,] versus time. 3. Plot of 1/[KIO,] versus time. 4. Plot of initial concentration [H,S0,] versus time. 5. Plot of In[H,SO,] versus time. 6. Plot of 1/[H,SO,] versus time.Explanation / Answer
Suppose the reaction mixture is made by mixing 1ml of 0.1M KIO3 with 4 ml of 0.2 M H2SO3 for the reaction,
KIO3 + 3H2SO3---->KI+3H2SO4
Initial concentration of KIO3=[KIO3]o=moles of KIO3 in the reaction mixture/total volume of the mixture=(1ml*0.1mol/L)/(1ml+4ml)=(0.001L*0.1mol/L)/(0.005L)=0.02 mol/L=0.02M
Similarly ,initial concentration of H2SO3=moles of H2SO3 in the reaction mixture/total volume of the mixture=(4ml*0.2mol/L)/(1ml+4ml)=(0.004L*0.2mol/L)/(0.005L)=0.16 mol/L=0.16M
