I am performing rate of reaction studies on hydrogels with 2 monomers and crosslinker. We can look at absorbance of a single wavelength of light over the course of the reaction through UV-Vis to determine our reaction rate, but I don't understand how that would relate to rate constants within the equation. I'm having a hard time finding resources to understand the kinetics on my own, so I'm hoping maybe someone here has already dealt with this problem and can point me in the right direction. Thanks.
