How to calculate rate constant for first order reaction?

WebYou can use the Arrhenius equation to show the effect of a change of temperature on the rate constant - and therefore on the rate of the reaction. If the rate constant doubles, for … WebThe integrated rate law for the second-order reaction A → products is 1/ [A]_t = kt + 1/ [A]_0. Because this equation has the form y = mx + b, a plot of the inverse of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to k. Created by Jay. Sort by: in and out burger locations in ctWebFeb 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.
