I2 (aq) + CH3COCH3 (aq)  HI (aq) + ICH2COCH3 (aq)Iodine in solution has a yellow-brown color, whereas the acetone and both products are colorless. This means that we can run the reaction using iodine as the limiting reagent, and when we see that the yellow-brown color of the iodine has disappeared, we know that the reaction has stopped and all of the iodine has been consumed. Recall that to calculate a rate of reaction, we would like toknow the change in concentration of a reactant or product during a fixed amount of time. Wewill choose the reactant iodine in this case, because its brown color allows us to determinewhen its concentration has fallen to zero. Rate = –Δ[I2] / Δt = – ([I2]final – [I2]initial) / ([tfinal – tinitial) = – (0 – [I2]initial) / (tfinal – 0) = [I2]initial / tfinal Run several trials at different concentrations of reactants and use themethod of initial rates to obtain values for k, x, y, and z in the rate law. Rate = k [I2]x [acetone]y [H+]z Run the…

In the reaction: Cr2O72- + 6S2O32- + 14H+ → 2Cr3+ + 3S4O62- + 7H2O, S2+ is being reduced. TRUE OR FALSE
In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99
average cycle time with the doubled KBrO3 concentration is 40 and average cycle time with initial KBrO3 concentration is 74.

The exhaust systems of cars today are equipped with catalytic converters that uses rhodium and platinum as catalysts. No more than 4-9 grams of these precious metals are used in a single converter. This catalyst speeds up reaction of three types of toxic compounds given off the cars. The rhodium and platinum as catalysts do not enter into a chemical reaction, but the rough surface of the catalyst provides a high-surface area for the reaction to occur. Catalytic converters change unburned hydrocarbons, carbon monoxide, and nitrogen oxides into harmless compound. Why is it not necessary to add more rhodium and platinum to a catalytic converter as these substances are used?
