How to solve rate constant
WebFeb 26, 2014 · 1 Answer. Sorted by: 7. We assume 1 st order kinetics in hypochlorite and 1 st order kinetics in the color. Putting this in the equation we get the following: d [ Red] d t = − k [ Red] 1 [ bleach] 1. Because you keep the concentration of bleach the same throughout the trial, you can write. k obs = k × [ bleach]
