WebA We can calculate the half-life of the reaction using Equation 3: t 1 / 2 = 0.693 k = 0.693 1.5 × 10 − 3 min − 1 = 4.6 × 10 2 min Thus it takes almost 8 h for half of the cis-platin to hydrolyze. B After 5 half-lives (about 38 h), … WebThe formula for the half-life is obtained by dividing 0.693 by the constant λ. Here λ is called the disintegration or decay constant. Hence the formula to calculate the half-life of a … scuff cover vs shoe polish
