It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. Determining a Half Life. At 400K the half-life for the decomposition of a sample of a gaseous compound initially at 555 kPa was 340s.
T ½ A o 2k For a first order reaction A products rate kA.
Graphical relations and half lives. For a first-order reaction the half-life is given by. So lets get some space over here. In each succeeding half-life half of the remaining.
