How to determine rate law from table
WebRearrange the equation to make k the subject and solve to find k. To calculate the rate constant using half-life: Convert the half-life of the reaction into seconds. Substitute this value into the equation and solve to find k. The rate constant relates to the Arrhenius equation with the formula k = A e − E a R T. WebFor example, an integrated rate law is used to determine the length of time a radioactive material must be stored for its radioactivity to decay to a safe level. ... Table 18.4.1.
