WebFirst order reaction: For a first order reaction the half-life depends only on the rate constant: Thus, the half-life of a first order reaction remains constant throughout the reaction, even though the concentration of the reactant is decreasing. ... Since the reaction is first order we need to use the equation: t 1/2 = ln2/k . t 1/2 = ln2/(1. ... WebHalf-life equation for first-order reactions: t1/2 = k0.693 where t1/2 is the half-life in seconds (s), and k is the rate constant in inverse seconds (s−1). Part A To calculate the …
