a The gas arsine, AsHz, decomposes as follows: 2AsH3(g) = 2As(s) + 3H2(g) In an experiment at a certain temperature, pure AsH3(g) was placed in an empty, rigid, sealed flask at a pressure of 385.0 torr. After 48 hours the pressure in the flask was observed to be constant at 482.0 torr. Calculate the equilibrium pressure of H2(g). Pressure = atm Calculate K, for this reaction. K,=

5.20 mol of solid A was placed in a sealed 1.00-L container and allowed to decompose into gaseous B and C. The concentration of B steadily increased until it reached 1.40 M, where it remained constant Then, the container volume was doubled and equilibrium was re-established. How many moles of A remain? Number mol A

1.100 mol phosphorus pentachloride, PCl5 were placed in an empty, sealed, 2.00 L container at room temperature, when PCl5 is a solid. Then temperature was raised to 250oC, all the chemical evaporated, and it was found that 45% of it (by mass) decomposed according to the equation: PCl5(g) PCl3(g) + Cl2(g) (a) What are the equilibrium molar concentrations of all three chemical compounds involved? (b) What is the equilibrium constant K for that rxn?
