(a)
Interpretation:
The plot that would yield a straight line and helps in determining the parameters a and b should be determined.
Concept introduction:
A hazardous waste needed to be disposed. So, the solution of this waste is pumped into a storage tank. Then, the solution subjected to chemical treatment. Due to the chemical treatment, the concentration (C) of the decomposing waste has been reported to vary with time (t) according to the formula.
Where a and b are constants.
(b)
Interpretation:
The value of a and b should be estimated using graphics software. The graph of C vs t to show both measured and predicted values should be plotted.

- Water at 60° F is being pumped from a stream to a reservoir whose surface is 210 ft above the pump. The pipe from the pump to the reservoir is an 8-in Schedule 40 steel pipe 2500 ft long. The pressure at the pump inlet is - 2,36 psig. If 4.00 ft³/s is being pumped, a). Compute the pressure at the outlet of the pump. Answer: 0,997 MPa b). Compute the power delivered by the pump to the water. Answer: 151 hp Consider the friction loss in the discharged line, but neglect other lossesarrow_forward1.

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?
