The t 12 formula for a zero order reaction suggests the half-life depends on the amount of initial concentration and rate constant. Half-life refers to the amount of time it takes for half of a particular sample to react. So solve for T one half or our half life.
Notice this is very different for the half-life for a first order reaction.
For a zero-order reaction the mathematical expression that can be employed to determine the half-life is. T ½ 1 k A o Top. So solve for T one half or our half life. 244 t 1 2 ln.
