In H2 (g) + I2 (g) = 2HI (g), the initial reactions H2 and I2 are each equal to 1 mol / L. Calculate the equilibrium concentrations of substances if the equilibrium constant is 50.

When a chemist collects hydrogen gas over water, she ends up with a mixture of hydrogen and water vapor in her collecting bottle. if the pressure in the collecting bottle is 97.1 kilopascals and the vapor pressure of the water is 3.2 kilopascals, what is the partial pressure of the hydrogen?
