WebDefinition and Formula. Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not. One of the most well-known applications of half ... WebFeb 12, 2024 · Since the reaction order is second, the formula for t1/2 = k-1 [A] o-1. This means that the half life of the reaction is 0.0259 seconds. 3 Convert the time (5 minutes) to seconds. This means the time is 300 seconds. Use the integrated rate law to find the final concentration. The final concentration is .1167 M. References WebMay 22, 2016 · The rate for this order is rate = k [A].
