Answer the following questions for the following equilibrium reaction: 2A + B ↔ 2C Given a basis of 150 mol/min component A: a. How much component B should be fed to have 200% excess B? b. Write equations for the mole flows of each component as functions of feed rate and the extent of reaction (). c. The equilibrium constant, K, is 75 at the reaction temperature. What is the extent of reaction? d. What is the composition at equilibrium? Please give your answer in terms of vapor phase mole fractions.
1. The kinetics of an enzyme-catalyzed reaction is described as r = (1+ aI)(K1 + S)* The following data were obtained in rate studies conducted in a well-mixed steady state continuous flow reactor using the same enzyme loading. S (mol/L) I (mol/L) r (mol/{L.min}) | 4.3 0.6 0.3 0.5 0.05 3.8 2.1 The experimental data should provide enough relations for the unknown kinetic parameters, rm, K1, and a (no need to use linear regression). Solve the relations to obtain the parameter values.
give handwritten answer-A+B -> X (kx) A+B -> Y (ky) A+B -> Z (kz) The substances A and B (with the initial concentration CA0=3 M and CB0=1 M) react in parallel (competing) reactions. What are the individual rate constants (kx,ky,kz) knowing that at the end of the reaction the proportions of the X,Y,Z are 8%, 91%, 1%, and after the first half hour the concentration of A becomes 2.2 M. The answer should be: kx = 1.73 x 10^(-3) L/mol*s ky = 1.97 x 10^(-2) L/mol*s kz = 2.17 x 10^(-4) L/mol*s
Explosions occur when the rate of reaction increases dramatically over a short period of time. There are several types of explosions such as autocatalytic explosions, thermal explosions and branched chain explosions. The mole balance of radical species in branched chain reaction can be expressed as: (Refer attachment) With appropriate assumption, prove that the branched chain explosion can occur exponentially and provide two (2) ways to prevent the occurrence of radical chain explosion in chemical laboratory.
The rate of a certain reaction is given by the following rate law: rate =kNO2O2 Use this information to answer the questions below. What is the reaction order in NO? What is the reaction order in O2? What is overall reaction order? At a certain concentration of NO and O2, the initial rate of reaction is 5.0 x 104 M / s. What would the initial rate of the reaction be if the concentration of NO were doubled? Be sure your answer has the correct number of significant digits. Ms The rate of the reaction is measured to be 40.0 M / s when [NO] = 0.57 M and [O2] = 2.0 M. Calculate the value of the rate constant. Be sure your answer has the correct number of significant digits. =k⋅M−2s−1
4.33 Consider the reactions A → B, B → C, A → D, T₁ = k₁CA r₂ = k₂CB r3 = k3C² with B the desired product. (a) How would you describe this reaction set? (b) Should one use a PFTR or CSTR, and is there an optimum residence time? [The answer depends on the relative ks.] (c) Find C; (T) in PFTR and CSTR if r3 = k3CA.
For the following reaction set, define or propose two types of reactor systems to maximize product D selectivity, sketch the reactor system and describe clearly the input reactant concentrations and separation requirements if necessary. The unit of reaction rate is in units (mol/dm^3.sec) and concentration in units (mol/dm^3). (question on picture)
