Kc value A critical step in the industrial production of sulfuric acid involves the oxidation of sulfur dioxide to sulfur trioxide called the contact process: 2SO2(g) + O2(g) -> 2SO3(g) Change in H degree = -198kJ Although the value of Kc for the reaction is very large at room temperature,m its reaction rat…
Isomerization reaction concentration The isomerization reaction, CH3NC -> CH3CN, is the first order and the rate constant is equal to 0.48 s-1 at 600 K. (a) What is the concentration of CH3NC after 0.20 minutes if the intial concentration is 0.10 M?

ORGANIC HELP!!!! why does it take a temperature of almost ,800 degrees C to melt NaCl, but stirring in water at room temperature will also effect a break-up of the lattice?
Angular Momentum Vector The power output of an autmobile engine is advertisted to be 220 hp at 600 rpm. (Remeber 1 hp = 7446 Watts) a) What is the corresponding torque of this engine at that rpm? b) You could apply this much torque if you placed a heavy weight at the very end of […]
Fischer esterfication In the Fischer esterification reaction, a carboxylic acid reacts with an excess of alcohol in acidic conditions to form an ester. During the reaction the sp2 hybridized carbonyl carbon of the acid forms an sp3 hybridized intermediate before returning to sp2 hybridization in the product. Draw the str…
Calculate the concentration of each of the following solutions in mass percent. So lost 9.95g C2H6O in 69.1g H2O 118 KCl in 628g H2O 30.3 Mg KNO3 in 2.24g H20 Please help. I’m so lost on this question. I thought it would be for example.. 9.95/(9.95+69.1) but that was wrong. Please, please help.
Rate Equations A given reaction has an activation energy of 14.5 kJ/mole. This reaction is normally run at room temperature (25C) and takes about an hour to get to completion. At what temperature should the reaction be run so that it is running twice as fast as at room temperature? 1. 98 C 2. 77 […]
