A zero-order reaction (A rightarrow B) is known to be 40% complete after 30 minutes in a batch reactor. How long is required to achieve 95% completion? Assume the initial concentration of the reactant is 100 mg/L.
Compare and contrast how first-order reaction kinetics and zero-order reaction kinetics differ in terms of the depletion of a reactant A in a chemical reaction. Assume an initial concentration of 420 mg of A. Assume a half-life of 30 minutes if first-order kinetics are obeyed, and a depletion rate of 60 mg/hour if zero-order kinetics are obeyed. Use a clearly drawn graph(s) to determine which rate will result in complete depletion of A over the shortest time. Assume 99% to...

Exercise 2.6. After 8 minutes in a jacketed batch reactor, 80% of reactant A is converted (ao = 1 mol L-1). After 18 minutes, the conversion is 90%. Knowing this information, find the kinetic order and calculate the value of the reaction rate for that order of reaction when the concentration of A inside the reactor is 0.2 mol L-1 ADDITIONAL DATA: The density of the reacting mixture does not change with conversion.
