Answer:
4.36 ppm
Explanation:
First we convert percent transmittance to absorbance:
Then we <u>calculate the concentration of the solution</u>, using <em>Lambert-Beer's equation</em>:
It is usually used with molar concentrations but given that the given absortivity is in ppm terms and the answer is also in ppm, we can simply use the given value.
- 0.268 = 6.14x10⁻²L·ppm⁻¹ * 1.00 cm * C

Reaction rates are usually expressed as the concentration of reactant consumed or the concentration of product formed per unit time. ... The graph shows the change in the number of A and B molecules in the reaction as a function of time over a 1 min period (bottom)
