Chapter 9, Problem 9.10P
It has been observed that substrate inhibition occurs in the following enzymatic reaction:
E + S → P + E
- (a) Show that the rate law for substrate inhibition is consistent with the plot in Figure P9-10B of −rs (mmol/L · min) versus the substrate concentration S (mmol/L).
- (b) If this reaction is carried out in a CSTR that has a volume of 1000 dm3, to which the volumetric flow rate is 3.2 dm3/min, determine the three possible steady states, noting, if possible, which are stable. The entrance concentration of the substrate is 50 mmol/dm3. What is the highest conversion?
- (c) What would be the effluent substrate concentration if the total enzyme concentration is reduced by 33%?
- (d) List ways you can work this problem incorrectly.
- (e) How could you make this problem more difficult?

Figure below shows a portion of a fire protection system in which apump draws water at 60 F from a reservoir and delivers it to point B at the flow rate of 1500 gal/min
a). Calculate the required height of the water level in the tank in order to maintain 5.0 psig pressure at point A. Answer: h = 12,6 ft
b). Assuming that the pressure at A is 5.0 psig, calculate the power delivered by the pump to the water in order to maintain the pressure at point B at 85 kPa. Include energy lost due to friction but neglect any other energy losses. P₁ =19,2 hp

The reaction conversion rate is 35%. The temperature increase in heat exchanger 2 is adiabatic. A fresh stream of pure ethylbenzene (25°C) enters a mixing vessel, where it is combined with a recycle stream (from the distillation column, as explained later), which also consists of pure ethylbenzene at 25°C. After mixing, the stream is sent to a heat exchanger (HX1), where the mixture is heated to 200°C. Next, the mixture enters an adiabatic heat exchanger (HX2), where it is further heated to 300°C by adding steam (at 350°C). This steam is used to prevent side reactions and carbon deposition in the reactor. The heated mixture is then fed into the reactor, where the reaction takes place with a conversion rate of 35%. As a result, the mixture cools down to 260°C. The resulting mixture is then sent to HX4, where…arrow_forwardChemical Engineering Questionarrow_forward
- 4.16 aarrow_forward8. The thermal decomposition of nitric oxide at elevated temperatures 2NO → N₂+02 has been studied in a batch reactor where at temperatures below 2000K the rate expression that applies to low conversions is: r = kCm05 Co At high conversions, or when the initial mixture contains a high concentration of O2 the rate expression is given by: r = k' Cм0.5 C15C0,5 To explain these kinetics the following chain reaction mechanism has been proposed: Initiation: Propagation: 2NON₂O +0 k₂ E1=272.0 kJ/mol 0+ NO O₂+ N E₂-161.0 kJ/mol N+NO N₂+0 E3-1.4 kJ/mol K4 20+ MO₂+M E4=14.0 kJ/mol ks Termination: where M is any molecule capable of the energy transfer necessary to stabilize the oxygen molecule. Once appreciable amounts of O2 are present in the reaction mixture, the initiation reaction that is the primary source of atomic oxygen is no longer the first reaction. Instead, the following reaction begins to dominate the chain initiation process: Initiation (high O2): ks NO +0₂ NO₂+0 E5=198.0 kJ/mol a.…arrow_forward2:41 2) If the number-average degree of polymerization for styrene obtained by the bulk polymerization at 25°C is 5,000, what would be the number-average degree of polymerization if conducted in a 10% solution in toluene (900g of toluene per 100 g of styrene) under otherwise identical conditions?
