Half life method for reaction order

Webconstant for a fust-order reaction, consistent with eq 5. Half-life methods can be further simplified if the two half lives are suc- cessive, i.e., if the second half life begins where the fnst half life ends. In this case [AIo’ = [A], and [AI0’’ = [A],/2. Substituting these relationships into eq 6 gives, for n = 1, . WebThis video shows how to determine the reaction rate law using the integrated rate laws and the half lives of chemical reactions with one reagent that are either 0th, 1st, or 2nd-order.
