. The transformation of glucose into fructose by the enzyme glucose isomerase, was carried out in two different types suspended-enzyme bioreactors: 1) CSTR, and 2) plug flow reactor. The process obeys Michaelis-Menten kinetics. The following parameters and kinetic constants were kept the same in both bioreactors: $ So (input substrate concentration) = 1.0 mMol/L; $ F (volumetric flow rate) = 1.0 m3/h; $ Km = 7x10-4 Mol/L; $ Vmax = 0.2 mMol/(L.h) Determine: $ Volume of CSTR for 50% conversion of glucose; $ Volume of PFR for 50% conversion of glucose; $ Volumes of CSTR and PFR in series (assume that the volumes are equal) in two cases: $ first CSTR $ first PFR 2. Calculate the volume of a stirred tank bioreactor containing the same enzyme, but immobilized on the surface of a flat-geometry support. The value of the mass-transfer coefficient is 0.6 h-1. The values of the rest of process parameters are the same as above.

What is a reaction in a balancing equation?
When an equation is balanced, the rate of the forward reaction equals the rate of the reverse reaction.
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
What is the k in the rate law equation?
A rate constant
How can the rate be determined from the rate law?
You need to know the rate of the reaction, as well as the concentrations of all reactants. Then you plug those values into the equation of rate = k[A][B] or whatever the rate equation happens to be.
How can rate constants be determined from the rate law?
You need to know the rate of the reaction, as well as the concentrations of all reactants. Then you plug those values into the equation of rate = k[A][B] or whatever the rate equation happens to be.

What is the k in the rate law equation?
A rate constant
What is rate laws?
An equation that relates the reaction rate to the concentration of the reactants
What is an Arrhenius equation?
An Arrhenius equation is an equation which approximates the dependence of the rate of any chemical reaction on the temperature.
What is a rate law?
An equation that relates the reaction to the concentrations of the reactants

What is relative rate constant?
A relative rate constant the rate at which a reaction will take place. Ex. V = k [A][B] the constant ,k, is a constant value for the rate of the reaction in said equation.
How can rate constants be determined from the rate law?
You need to know the rate of the reaction, as well as the concentrations of all reactants. Then you plug those values into the equation of rate = k[A][B] or whatever the rate equation happens to be.
What is a 1.5 order of reaction?
A + B --> C has non-elementary reaction rate equation -rA = kCACB1/2 The exponent of CA is 1, the exponent of CB is 1/2, for an overall reaction order of 1 + (1/2) = 1.5. Do not let the stoichiometric coefficients from the reaction mislead you. It has to do with the rate equation for a given reaction, not the (net) chemical reaction itself.
Who created the Arrhenius equation?
The Arrhenius equation was created by Svante Arrhenius in 1889, based on the work of Dutch chemist J. H. van't Hoff. The rate equation shows the effect of changing the concentrations of the reactants on the rate of the reaction.
Is rate constant equal to one over TIME in the Arrhenius Equation If so or not is there an equation representing their relationship?
The unit of the rate constant in a 1st Order reaction rate equation (NOT the 'Arrhenius equation', as stated in the question) is One over Time.General form of a reaction rate equation :rate (mol.L-1.time-1) = [rate constant(Ln-1.mol1-n.time-1)]*[Concentration()]nwhere:* n is the Order of the rate equation (that is of the rate limiting step) * all units are (italicalised) between brackets It can easily be seen in this that for n=1 (1st Order) the equation is:r = k * C1and in units:mol.L-1.time-1 = (L0.mol0.time-1)*(mol.L-1)1so:(mol.L-1.time-1) = (time-1)*(mol.L-1)Only the value of the rate constant k is depending on temperature only (cf. Arrhenius equation), though temperature is NOT in its unit.
