Water is converted in a boiler from saturated liquid at 500 kPa to superheated steam at 500 kPa and 300*c. Find the change in entropy and the heat transfer required.
Consider the combustion of ethylene, C2H4(g) + 3O2(g) ----> 2CO2(g) + 2H2O(g). If the concentration of C2H4 is decreasing at the rate of 0.025 M/s, what are the rates of changes in the concentration of CO2 and H2O?
In a refrigerator cycle low saturated liquid enters an evaporator and exits as saturated vapor. Draw the T vs. S curve for this cycle and shade the area that represents the cooling delivered by the refrigerator.
How does the presence of impurity B affect the solubility behavior of solute A? Do the solubilities of the two substances add together? Can each of them be treated separately?
Find the cooling achieved and the work by the compressor. Is the compressor isentropic? IF the cooling is 300 KJ/kg and the work by the compressor is 300 kJ/kg what is the coefficient of performance for the system?
Why is benzyne such a reactive molecule/why is it so unstable? (Is there any reason other than the fact that triple bonds are not stable within a 6-membered ring?)
When CO2 is bubbled through an ether solution of benzyl magnesium bromide, and the resulting mixture is acidified, phenyl acetic acid is produced. Any unreacted benzyl magnesium is converted to toluene.
The acid-dissociation constant for hypochlorous acid HClO is 3.0 x 10^- 8. Calculate the concentration of H3O^ + at equilibrium if the initial concentration of HClO is 7.5×10^-3 M.
