What is the rate constant of a first-order reaction that takes 127 seconds for the reactant concentration to drop to half of its initial value?

Expert Solution

A:- Equation for first order reaction half life, t_1/2 = 0.693 / k

127 sec. = 0.693 / k

k = 0.693 / 127 sec.

k = 0.0054567 sec^-1

Consider a CSTR where a simple first-order reaction takes place. The rate constant depends on the reactor temperature and can be given the Arrhenius equation. The reactor contents are cooled by a coolant that flows through a jacket around the reactor. Derive the dynamic model of the CSTR. i.e. the change of concentration of component A and the temperature of the reactor, assuming the flow rate and the inlet conditions are constant. You can use linearization technique for this coupled...
