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. WebThis is shown in the top graph. Given that the gradient of a concentration-time graph represents the rate of reaction, this gradient must be constant for a zero order graph. So a concentration-time graph for a zero order graph is a straight line with a negative gradient (the reactant is being used up as the reaction proceeds).
