Question

A. The gas phase decomposition ofSO2Cl2, SO2Cl2 yeildsSO2+Cl2 is first order omSO2Cl2. At 600K the half life for thisprocess is 2.3*10^5 s. what is the rate constant at thistemperature? B. At 320C the rate constant is 2.2*10-5 s-1. what is the half life at this temperature. A. The gas phase decomposition ofSO2Cl2, SO2Cl2 yeildsSO2+Cl2 is first order omSO2Cl2.

Explanation / Answer

A) SO2Cl2, SO2Cl2 yeildsSO2+Cl2 is first order reaction. so rate constant k is related to half life t as : kt =ln2 => k =ln2/(2.3x10^5) = 3.013 x 10^-6 Rate constant = 3.013 x 10^-6 ------------------------------------------------------------------------------------ B)at all temparatures , for a first order reactionkt=ln2 => half life t = ln2/(2.2 x 10^-5) = 0.315 x10^5 Half life = 0.315 x 10^5
