The term is also used more generally to characterize any type of exponential or non-exponential decay. 2 0693 into the equation results in the expression for the half-life of a first-order reaction. Thus for a first-order reaction each successive half-life is the same length of time as shown in Figure 1 and is independent of A.
The rate constant k for the reaction or enough information to determine it.
Nt N0 05 tT. A half-equation shows what happens at one of the electrodes during elect. Half-life or t½ is the time that elapses before the concentration of a reactant is reduced to half its initial value. The formula for half-life in chemistry depends on the order of the reaction.
