WebIt is possible to determine the probability that a single atomic nucleus will "survive" during a given interval. This probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and ... WebHalf-Life Formula. It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1/2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1/2 = 0.693/k.
