I need help with a Chemistry question. All explanations and answers will be used to help me learn.
One file is for Lab Report Guidleines and one is an example lab report.
These are the lab instructions:
In this experiment, the source of SO32– will come from sodium sulfite, Na2SO3, in the starch solution. When the sulfite ion (SO32–) reacts with the iodate ion (IO31–), it will produce iodine (I2). The iodine (I2) will then form a complex with starch, and produce a dark-blue color. This dark-blue complex can be used as an indicator to indicate the completion of the reaction.
The reaction order with respect to one of the reactants in the rate law can be determined by keeping the concentrations of all of the other reactants in the rate law, constant. In this experiment, there will be a total of four runs, each with a different initial concentration of iodate ion (IO31–). The concentration of iodate (IO31–) will be varied, while the concentration of the only other reactant, the sulfite ion (SO32–), in the rate law will be kept constant.
Watch the experiment demonstration, and write a lab report using the data plot the time and concentration for both the 1st Order and 2nd Order plots, as described in Chapter 13, section 13.4 “Graphing Kinetic Date”. Choose the best-fit line to determine the Reaction Order. Then using the slope of the plot chosen, determine the value of the Rate Constant.
