An alternative method of determining the reaction order is to measure the half-life ti/2 a function of initial concentrations. The half-life is simply the time necessary for x to become equal to one-half the initial concentration. (Any other fraction of the initial concentration would serve equally well.) From the integrated rate equations, it can be seen that for a first-order reaction [cf. Eq. (1-10)]... 

At 20°C, Waring-Blender Method was used to determine mass fraction of foaming agent foam properties, the integrated value of the foam was calculated, foam integrated value was the product of foam volume and half-life values. The experimental results showed in Figure 1.
