The mean velocities of HCl gas and NH3 gas at 25 degrees Celsius are 450m/s and 660m/s respectively. With these speeds in mind, briefly explain why so much time was required for the HCl and NH3 to meet in the glass tube
A solvent for an industrial process requires the use of phenol or benzene. Both are about the same in effectiveness for the process, and of course, gloves will be used when handling either solvent
Calculate the equilibrium concentration of each compound if 3.10 moles of COBr2 are placed in a 3.00 liter flask at a certain temperature. Kc = 0.140 for the reaction at this temperature.
A reaction was conducted in benzene as the solvent. Because the reaction was very exothermic, the mixture was cooled in a salt-ice bath. This was a bad choice. Why?
