Hydrogen chloride reacts with oxygen to yield chlorine and water. An equilibrium can be established with this reaction. An experiment was performed in a closed vessel starting with a mixture of 0.50 M HCl and 0.050 M O2. The amount of chlorine was monitored until no change was observed, at 0.048 M chlorine.
a) Which way did the system shift to achieve equilibrium?
b) What is Kc for this reaction, and what are the equilibrium concentrations of all relevant components?
c) What is Kp for this reaction if the final temperature is 25 oC?
Suppose you decide to define your own temperature scale using the freezing point (13 C ) and boiling point (360 C) of oleic acid, the main component of olive oil
A hypothetical gas obeys the equation P=RT/(V-b)-a/V. Does this gas exhibit a critical point? Why or why not
If yeast were supplied with glucose labelled with 14C at the C-1 position to produce ethanol and CO2 anaerobically, would the label appear in the CO2
An aqueous solution was prepared to have a density of 1.54 g/mL and a molarity of 19.4 mol/L at 20oC. The molar mass, Mm, of the solute is 40.00 g/mol. What is the mass of the solvent?
Wpump = 1500 kJ/h = 0.42 kW Qboil = 2.59 x 106 kJ/h = 718.7 kW Wturb = -227,300 kJ/h = -63.1 kW Qcond = -2.36 x 106 kJ/h = -656 kW What is the efficiency of the engine? How should we define it?
