At a particular temperature, 12.0 mol SO3(g) is placed into a 3.0 L rigid container, and SO3(g) dissociates by the reaction:
2SO3(g) ? 2SO2(g) + O2(g)
At equilibrium, 3.0 mol SO2(g) is present. Calculate K for this reaction. What is the percent decomposition of SO3? (Answer: K = 5.6 × 10-2 M; % decomposition = 25 %)
what is the minimum rate that fresh air has to be supplied to the room so that the concentration of CO2 in the room doesn't exceed 0.500% by mole? Assume the room is well mixed, and the volume of the solid dry ice does not change. mol air/min
How much of each of the following substances would you add to water to prepare 1.50 L of a 0.90 M solution? NiCl2 from the salt NiCl2·6 H2O
In the reaction 2A -> X + Y, the initial concentrations are all 0.600 M. If the equilibrium constant is 1.20 x 10^6, what are the equilibrium concentrations
