equilibrium constant
Not what you're looking for?
1. Write the equilibrium constant expression (K) for the following reaction
CS2 (g) + 4H2 (g) --> CH4 (g) + 2H2S (g)
2. Write the equilibrium constant expression (K) for the following reaction
CuO (s) + H2 (g) --> Cu (s) + H2O (g)
3. Ammonium chloride is sometimes used as a flux in soldering because it decomposes upon heating:
NHCl (s) --> NH3 (g) + HCl (g)
The HCl formed removes oxide films from metal to be soldered. In a certain equilibrium system at 300ºC, 8.2g of NH4Cl is present. The partial pressures of NH3 and HCl are 2.0 atm and 5.0 atm, respectively. Calculate K at 300ºC.
