assume that gaseous hydrogen iodide is synthesized from hydrogen gas and iodide vapor at 50 degrees celcius where the equilibrium constant is 1.00 x 10^2. Suppose HI at 5.00 10^-1 M, H2 at 1.00 x 10^-2 M, and I2 at 5.00 x 10^-3 M are mixed in a 5.0 L container. Calculate all concentrations at equilibruim.
