The half-life of a first-order reaction under a given set of reaction conditions is a constant.

If two reactions have the same order, the faster reaction will have a shorter half-life, and the slower reaction will have a longer half-life.Then divide by the initial concentration, multiplying the fraction by 100 to obtain the percent completion.Solution: A We can calculate the half-life of the reaction using Equation 14.5.3: $$t_=\dfrac=\dfrac=4.6 \times 10^\;min$$ Thus it takes almost 8 h for half of the cisplatin to hydrolyze.The half-life of a first-order reaction is (to indicate a half-life) into Equation 14.5.1 gives $$ln \dfrac = ln 2=kt_ \tag$$ The natural logarithm of 2 (to three decimal places) is 0.693.
