Question During work, a manager has to track when trainees are at work and when they are absent, so it is impossible for a trainee to be at work and absent. If the probability that a trainee is absent is 0.43, and the probability that a trainee is at work or absent is 0.99, what is the probability that a trainee is at work?

Please note that "geometry" refers to the molecular or ionic geometry. A. The Lewis diagram for CO2 is: \( \ddot{O}=C=\ddot{O} \) Recall that for predicting geometry, double and triple bonds count as only one electron pair. The electron-pair geometry around the C atom in CO? is There are lone pair(s) around the central atom, so the geometry of CO2 is B. The Lewis diagram for SO2 is: \( \ddot{O}-\ddot{S}=\ddot{O} \) Recall that for predicting geometry, double and triple bonds count as only one electron pair. The electron-pair geometry around the S atom in SO? is There are lone pair(s) around the central atom, so the geometry of SO? is

The elementary reversible reaction of BD liquid-phase synthesis, PG + 2X \stackrel{k_1}{\rightleftharpoons} BD + ER is carried out in a plug flow reactor (PFR) the feed temperature of 450 K. The specific rate constant (k), where the units of k and T are m³/mol/s and K, respectively. The optimum ratio of reactants is used, which is equimolar. The concentration of the limiting reactant is 1 mol/m³. The equilibrium constant at 298 K is 549.8 L^{0.5}/mol^{0.5}. The heat of formation in kJ/mol unit for each species at 298K are found as follows: H_{PG} = -45; H_{X} = 55; H_{BD} = -15; H_{ER} = -3. The heat capacities of the species in J/mol/K are as follows: C_{pPG} = 50; C_{pX} = 26; C_{pBD} = 32; C_{pER} = 35 and assumed constant at the given temperature range. a) Make a plot of equilibrium conversion as a function of temperature and determine the adiabatic equilibrium temperature and conversion. b) What will be the productivity of BD in the adiabatic reactor if 95% of the equilibrium conversion is planned to achieve and 10 L/s of feed is set. Evaluate the ways to improve productivity by decreasing the feed temperature to 400 K or by introducing one inter-stage cooling and the second PFR with the same feed temperature. Estimate the size of all three adiabatic reactors by using Polymath.
