3. A chemical reaction that follows first-order kinetics has a measured reaction rate constant (i.e., kvalue) of 10 days-1 at 15°C. a) Using temperature coefficient of e = 1.072, calculate

the reaction rate constant at 20°C.a o b) Calculate the time required to reduce the concentration of the chemical from 100 to 10 mg/Lat 15°C and 20°C.
