A thermometer has a time constant of 10 s and behaves as a first-order system. It is initially at a temperature 30°C and then suddenly subjected to a surrounding temperature of 200°C. Calculate the 90 percent rise time and the time to attain 99 percent of the steady-state temperature. Repeat these calculations for a time constant of 5 s and compare the results with that of the previous case.

A stream of ozone-enriched air (3% ozone by volume) is bubbled into a reactor as part of a disinfection strategy. Water entering the reactor is free of ozone. KH = 0.011 M/atm and KLa = 18 h-1 for ozone in this system. Ozone (O3) dissolved in water is unstable. The kinetics of decomposition are complex, but the rate can be approximated as first-order with respect to dissolved ozone. The first-order rate coefficient is pH-dependent and, at pH 8.0 and 25 C, is 12 h-1 in the system of interest. Find the steady-state concentration (mg/L) of dissolved ozone in the effluent if the reactor is operated as a CMFR with a 15-min retention time
The 98% settling time is the time required for a second-order system to respond to within 2% of the steady response. An approximate formula for calculating this time is t98 = 4/3wɲ. Estimate t98 for 3 = 0.707 and wn = 1 rad/s and verify the adequacy of the approximation.
Determine three methods to increase the accuracy and reliability of the "Kinetic Study of a Bleaching Reaction Experiment." The major source of error in the determination of relative rates of reaction in kinetic studies is the unwanted oscillation generated by input variables. How can this be prevented in the Kinetic Study of a Bleaching Reaction Experiment?
The adsorption equilibrium isotherm for aqueous phenol solution and activated carbon can be determined from the following data: c kg phenol/m3 solution q kg phenol/kg carbon 0.3220 0.150 0.1170 0.122 0.0390 0.094 0.0061 0.059 0.0011 0.045 Determine the appropriate isotherm for this experimental run
A₂ = A + A (k₁ and k_₁ ) A+B → P (K₂) i) Solve for dP/dt using a pre-equilibrium assumption ii) Solve for dP/dt using the steady state approximation. (you'll solve a quadratic equation) ii) Show, and clearly state in words, which assumptions make your answer for (ii) become the same as (i)
The rate constant for the second-order decomposition of ozone to oxygen is 18×10³ m'/mol/hr at 135 °C. What will be the conversion of ozone in a constant volume, isothermal batch reactor after 1 hour at 135 °C assuming an initial concentration of 103 mol/m?? At this time, what will be the rate of decomposition of the ozone? Repeat this analysis for a temperature of 145 °C, assume the reaction is irreversible and an activation energy of 55 kJ/mol.
