1. In your own words, why is it important to consider atmospheric stability when evaluating pollutant/toxicants dispersion? 2. It is argued that in Industrial Hygiene, Hazard identification is the most important step. Do you agree or disagree with this statement? Justify your answer. A continuous stirring tank reactor (CSTR) is used for an exothermic polymerization reaction. It is estimated that 20J/s are generated when operating at a constant reaction temperature of 75C. Assume that the cooling system (which typically removes 20J/s of heat) were to completely fail for 5min. Explain how you will determine if the system is at risk of a runaway reaction. Be sure to identify all the substant properties, additional information and assumptions needed
