Example 1: Estimated Rate Constants The half-life of a first-order reaction was found to be 10 min at a certain temperature. What is its rate constant? Solution Use Equation 20 that relates half life to rate constant for first order reactions: k = 0.693 600 s = 0.00115s − 1 WebA few specific examples are shown below to further illustrate this concept. The rate law: rate = k[H2O2] describes a reaction that is first order in hydrogen peroxide and first order overall. The rate law: rate = k[C4H6]2 describes a reaction that is second order in C 4 H 6 and second order overall. The rate law: rate = k[H+][OH−]
