N2(g) + 3H2(g) <---> 2NH3(g) nh3 was synthesized at 200C in the presence of a powdered os catalyst leading to the equilibrium system represented above. Which of the following would result in more NH3 in the mixture after equilibrium is reestablished
A) Adding some N2(g)
B) Removing some H2(g)
C) increasing the temperature of the system to 250C at a constant pressure
D) replacing the powdered Os(s) with a solid cube of Os(s) of the same total mass

Amixture with the same composition throughout is!

16. in a reaction that has reached equilibrium, a. the forward and reverse reactions are occurring at the same rate. b. the reactants and products are in equal concentrations. c. the forward reaction has gone further than the reverse reaction. d. there are equal numbers of atoms on both sides of the equation. e. a, b, and d are correct.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
