(a) Write expressions for (i) the rate of generation of B in the first reaction and (ii) the rate of consumption of B in the second reaction. (If this takes you more than about 10 seconds, you're missing the point.) /dt, (b) Write mole balances on A, B, and C, convert them into expressions for dC /dt, dCB/ and dC/dt, and provide boundary conditions. A (c) Without doing any calculations, sketch on a single graph the plots you would expect to obtain of CA versus t, CB versus t, and C versus t. Clearly show the function values at t = 0 and 1 → ∞o and the curvature (concave up, concave down, or linear) in the vicinity of t = 0. Briefly explain your reasoning.

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.

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.

Q3: Ethyl ether is made by dehydration of ethyl alcohol in the presence of sulfuric acid at 140 °C 2C2₂H5OH →→C4H₁0O+H₂O A simplified process is shown in figure below. If 87% conversion of the alcohol fed to reactor occurs per pass stream in reactor. 1- Write the equations that simulate above process. 2- Perform the degree of freedom for the overall and sub processes (List your answer in table). Pure ethyl ether (1200 kg/hr) 93% H₂SO4 7% H₂0 Alcohol separation Dilute H₂SO4 solution Fresh feed 95% alcohol Reactor Ether separation Recycle 92% alcohol 8% water Waste Sulfuric acid and water
