A mixture of 30 mol% CO, 65 mol% H2, and 5 mol% N2 is fed to a methanol (CH3OH) synthesis reactor, where the following reaction occurs:
CO + 2H2------><____CH3OH
The reactor is at 200 degrees Celsius and 4925 kPa. The stream leaving the reactor is at equilibrium.
If 100 kmol/h of the feed mixture is fed to the reactor, calculate the flow rates of all species leaving the reactor.
The vapor pressure of water at 20°C is 17.5 mmHg. What is the vapor pressure of water over a solution prepared from 2.00 × 102 g of sucrose (C12H22O11, molar mass = 342 g/mol) and 3.50 × 102 g water? 1. 0.51 mmHg 2. 16.0 mmHg 3. 17.0 mmHg 4. 18.0 ..
How much heat (in J) is evolved or absorbed when a 36.9 g sample of water (specific heat = 4.18 J/(g K)) cools from 87.7oC to 79.2oC
The acid forms two ions, HC2O4- and C2O42-, by the sequential loss of H+ ins. Draw lewis structures for the three species and comment on the relative lengths and strengths of their carbon-oxygen bonds.
Derive an expression for (δU/δV)T for a gas that obeys the van der Waals equation of state.
How many grams of Na3PO4 will be needed to produce 500ml of a solution that has a concentration of Na ions of 0.600M
Calculate the mass of propylene glycolC3H8O2 that must be added to 0.320kg of water to reduce the vapor pressure by 2.88torr at 40C Pressure H2O 40C 55.3torr
If 17.2 mL of 0.800 M hydrochloric acid solution are required to neutralize 5.00 mL of a household NH3 solution, determine the molar concentration of the NH3,ammonia?
Potable water (drinking water) should not have manganese concentrations in excess of 0.05 mg/mL. If the manganese concentration is greater than 0.1 mg/mL, it imparts a foul taste to the water and discolors laundry and porcelain surfaces.
Draw a phase diagram labeling all the above points. Also label the melting point curve, the boiling point curve, and the solid, liquid, and gas regions.
Assuming that the calorimeter absorbs only a negligible quantity of heat and that the density of the final solution is 1.0 g/mL, calculate the enthalpy change per mole of BaSO4 formed.
Predict the rate of change in the concentration of N2O over this time interval. In other words, what is dt [N2O]/ dt?
What is the difference between selectivity and sensitivity as these words pertain to sensors? Why or why not would you want a very sensitive sensor?
