Q2. A chemical reaction follows second-order kinetics, and the rate constant is given by the equation: k=2.54103exp(T45.6) where k is the rate constant (L/mol.s) and T is the temperature in Kelvin. a) What are the units of 2.54103 and -45.6 ? b) Calculate the rate constant in L/mol.s for a temperature of 20C. c) Derive a formula for k(molmingal) as a function of T(K)
