Rate = 0.04CACB = 0.04 CA0 (1-x) (CB0 - CA0x) = 0.04 CA0 (1-x) CA0(M- x) = 0.1156 (1-x)(1.765-x)
Here M = CB0 / CA0 3/1.7 =1.765
For batch reactor

acetaldehyde (CH3CHU) in aqueous For the reaction between hydrocyanic acid (HCN) and solution, HCN(A) + CH3CHO(B) - CH2CH(OH)CN the rate law at 25°C and a certain pH is(-ra)=KACACB, where ka=0.210 L mol"min" (see problem 4-6). If the reaction is carried out at steady-state at 25°C in a CSTR, how large a reactor (V/L) is required for 75% conversion of HCN, if the feed concentration is 0.04 mol L-l for each reactant, and the feed rate is 2 L min!?

1. Pure butanol (A) is fed to a semibatch reactor containing pure ethyl acetate (8) to produce butyl acetate (C) and ethanol (D). The liquid- phase reaction, A + B ㈠ C + D, is elementary and reversible and is carried out isothermally at 300 K. At this temperature, the equilibrium constant, Kc, is 1.08 and the specific reaction rate, k is 9 x 10 5 L mo s1.Initilly, there is 200 L of ethyl acetate in the reactor, and...
1. Acrylonitrile is produced by the reaction of propylene, ammonia, and oxygen C3H6 + NH3 + O2 C3H3N + 3H2O The feed contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar flow rates of all product gas constituents for a 30% conversion of the limiting reactant, taking 100...

Hi everybody,can you help me for problem 4 in the attach . Thank
for help!
The elementary reversible reaction A + B 2C occurs in the liquid phase in isothermal CSTR. A stream containing equimolar amounts of A and B in a solvent enters. the reactor, and the conversion of A is measured to be 60%. The equilibrium conversion o A under the same inlet conditions is known to be 80%. The volumetric flowrate into the process is to be...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
