The method of half-lives involved measuring the half-life’s dependence on concentration. The expected behavior can be predicted using the integrated rate laws we derived earlier.
WebDetermining a Half Life. To determine a half life, t ½, the time required for the initial concentration of a reactant to be reduced to one-half its initial value, we need to know: The order of the reaction or enough information … WebRadioactive isotopes are used for blood flow monitoring, cancer treatment, paper mills, carbon dating and smoke alarms.
