4) If the reaction SO2Cl2 → SO2 + Cl2 is first-order reaction. At 230oC, k = 0.125 hr-1. If the initial concentration of SO2Cl2 is 0.250 M, what is the concentration after 7.6 hours? How long will it take for the concentration of SO2Cl2 to drop to 0.0651 M? What is the half-life for this first order reaction?

For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0. A certain first-order reaction (A→products A → p r o d u c t s ) has a rate constant of 9.30×10−3...
