Question- What would the maximum input (influent) concentration be for a CSTR reactor operating at steady state that degrades the toxic chemical DDB if the treated effluent concentration must not exceed 5 µg/L? Consider that the influent flow rate is 0.5 gal/min and the decay reaction is characterized by a rate constant (-100 L/mg.s). The reactor has size of L: W: H = 4 m: 1 m: 0.5m.

Why is the boiling point of octane, C8H18, higher than that of methane, CH4, if they are both nonpolar molecules? 7-Using a diagram to illustrate your answer, explain the effect of temperature on the vapor pressure of a liquid.
The reaction CH3CH2NO2 + OH- → H2O + CH3CHNO2- obeys the rate law d[A]/dt = -k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25°C.
