In this lab we will be expressing rate as a change in concentration of reactants over time. In order to calculate this we need to know the initial concentrations of our reagents after they are combined but before the reaction occurs. This is a dilution process. Recall that the calculation for a dilution is accomplished using the relationship M1V1 = M2V2. Complete the columns in table 3 for the initial concentrations of [I-] and [Fe3+]. As an example: For each trial the total volume, including the starch, is 100.25 mL. We will be using 0.0500 M KI and 0.0500 M Fe(NO3)3. For trial #1: [Fe3+] = (0.0100 L x 0.0500 mol/L) ÷ 0.10025 L = 0.00499 M Your answers for questions 1-6 should each have 3 sig figs. Questions 1-6 will ask you to calculate the initial concentration of either [I-] or [Fe3+] for each trial. You should then put the answers in table 3 on your lab report. What is the initial [I-] for trial #1? What is the initial [I-] for trial #2? What is the initial [I-] for trial…
Would the exponents, m and n, in your rate expression be larger than, smaller than, or unchanged from the correct values as a result of each of the following mistakes? Indicate clearly your reasoning. Experiment 3: 20.0mL of 0.10M KI, 5.0mL of distilled water, 5.0mL H2O2 rate = k[H2O2]m[I-]n a) A leak occurred around stopper A in the mouth of the Erlenmeyer flask during experiment 3.

Two prominent gas-phase atmospheric reactions are written below with rate coefficients in units of cm3 molecule-1 sec-1 (T= temperature in K and [M] = the number density of air in molecules cm-3). Convert theserate constants to ppm-1 min-1, again assuming standard sea-level pressure and T = 288 K.i. O + O2 =O3 k = [M]*6.0*10^-34*(T/300)^-2.3ii. NO + O3 = NO2 + O2 k = 3.0*10^-12*e^(-1500/T)
Explain how the rate of reaction rate in pressure cookers was increased by including these subtopics: 1. Explain with collision theory and energy potential diagrams: how the rate of reaction is affected by temperature, surface area, nature of reactants, concentration, etc. by using collision theory? 2l Discuss whether the reaction is endothermic or exothermic (use Hess’s Law, Le Châtelier’s Principle, or Kinetic Molecular Theory to explain in increasing rate of reaction and relevance by including all 4 required subtopics )

These questions are based on a reaction rate lab for my Chemistry homework. I attached my data values that I have already calculated. I think I am supposed to show more work for 4 and 5. I am genuinely confused on how to plot the graph too (6-7). Lastly, I am not sure if I got 8-10 correct? I think the rate law might be Rate = k [HCl] [Na2S2O3] but I am not sure if it needs an exponent or not?
