A chemical reaction is found to have an activation energy (Ea = 15 kJ/mol). At a temperature of 505 K, what fraction of collisions have enough energy to exceed the activation energy
what specific property of diethyl ether is exploited here and why is it important to prevent the overheating of the reaction mixture?
The energy (in kJ) that is removed as heat from this system when the Carnot refrigerator from part a) contains 340. g of R-12. Assume the heat is removed in a constant pressure process.
60.0 mL portion of of 1.70 M solution is diluted to a volume of 288 mili litres. A 144-mili litres portion of that solution is diluted using 115 mLili litres of H2O. Determine the final concentration.
Provide a method for separating the mixtures of two or three compounds, dissolved in a solvent diethyl ether. In each case one of the components will be a neutral compound.
what mass of precipitate will form if 1.50 L of concentrated Pb(CLO3) is mixed with 0.550 L of 0.230 M NaI ? assume the reaction goes to completion.
Explain which element has higher ionization energy, Be or B. Start by comparing thier energy level diagram?
what product would you expect from the reaction of one equivalent of 1 propanol with phthalic anhydride ?
what effect does increasing the temperature have on equilibrium? what effect does adding a catalyst have on equilibrium?
The pH of the solution at equivalence was 8.4. At 9.3 mL the pH was 5.3. What is the Ka for this acid? Please show all the work
Gibbs Free Energy and Equilibrium The reaction SO2(g)+2H2S(g)?3S(s)+2H2O(g) is the basis of a suggested method for removal of SO2 from power-plant stack gases
what is the total pressure in the reaction flask at the end of the reaction? What are the partial pressures of the gases in the flask?
At 0.0oC, if the volume of air is 3.4 mL and the pressure of the atmosphere that day is 695 mmHg, what is the number of moles of air?
