How does the index of refraction of the unknown substance compare to the index of refraction of a vacuum? Explain how the speed and refraction of light would behave in both.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.
