You make dilutions of curcumin stock solution and measure the absorbance of each dilution to obtain the following data: Conc. (M
) Abs. 1.60E-05 1.93 1.21E-05 1.62 8.09E-06 1.08 4.04E-06 0.44 2.02E-06 0.13 Which data points should you keep when making your calibration curve? Choose all that apply. (Hint: Plot the data.)
1 answer:
Answer:
The following data point should be kept when making your calibration.
1.21E-05 M
1.60E-05 M
8.09E-06 M
4.04 E-06 M
Explanation:
From the graph it is obvious that the reading for the concentration 2.02E-06 M does not fall on the straight line. So this point should not be taken to construct the calibration plot.

<u>Answer:</u> The rate law expression for the given reaction is written below.
<u>Explanation:</u>
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
For the given chemical equation:
Rate law expression for the reaction:
Hence, the rate law expression for the given reaction is written above.
