Nitrogen and oxygen do not react appreciably at room temperature, as illustrated by our atmosphere. But at high temperatures, the reaction below can proceed to a measurable extent.
N2(g) + O2(g) ? 2 NO(g)
At 3000 K, the reaction above has Keq = 0.0153. If 0.2352 mol of pure NO is injected into an evacuated 2.0-L container and heated to 3000K, what will be the equilibrium concentration of NO?
What volume of 3 M H2SO4 is needed to neutralize all of the disodium salicylate and the excess NaOH (2.17 mL excess) present after the initial reaction?
Use stereoformulas to show that (S)-benzoin reduces to meso-hydrobenzoin.
The rate of vaporization of a liquid can be increased by 1)increasing the surface area 2)increasing the temperature 3)decreasing the
An atmospheric chemist studying the pollutant SO2, places a mixture of SO2 and O2 in a 2.00 L container at 800k and 1.90 atm. when the reaction occurs, gaseous SO3 forms, and the pressure falls to 1.65 atm
