A+BC 2. The decomposition of a compound follows a first-order kinetics with a rate constant of 0.0432s4 at 500C (a) If the initial concentration of starting material was 0.0500M, what is the concentration after 1.4min ? (b) How long (in minutes) will it take for the concentration of starting material to decrease from 0.750M to 0.000250M ? (c) How long (in minutes) will it take to convert 32 percent of the starting material? 3. This plot shows the rate of the decomposition of SO2Cl2 into SO2 and Cl2 as a function of the concentration of SO2Cl2. What is the order of this reaction with respect to SO2Cl2.? Note the axis
