How to solve for rate constant k

WebSo we were able to combine these two fractions. Now we're told the rate constant increases tenfold. So we can substitute 10 in for a K. For the catalyst reaction and one in for the non catalyzed reaction. So the un catalyzed reaction you can see is that they K. Value that is reflective of the statement here. So Kay very constant increases tenfold. 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] Now, we can continue onwards as follows:
