Calculate the equilibrium constant (K eq ) for the following system at 250 o C:PCl 5(g) PCl 3(g) + Cl 2(g)
At equilibrium, the gases in the flask had the following concentrations:
[PCl 5(g) ] = 0.012 mol/L, [PCl 3(g) ] = 0.015 mol/L, and [Cl 2(g) ] = 0.015 mol/L.
When gasoline burns in a car engine, the heat released pushes the pistons outward. If the expanding gases do 451 J of work on the pistons and the system loses 325 J to the surroundings as heat, calculate the change in energy.
