Question- A mixture consisting of 0.150 M N2(g) and 0.612 M H2(g) reacts and then reaches equilibrium according to the equation: N2(g) + 3H2(g) --->2NH3(g) At equilibrium, the concentration of ammonia is 0.213 M.
Calculate the concentration (molarity) of H2(g) at equilibrium
Rework your solution from the beginning and check each step carefully.
Concentrations of aerosol constituents are sometimes expressed as ppb (mole fraction) to enable comparison with gaseous concentrations expressed in ppb. The unit ppb (mole fraction) is evaluated as RT x concentration of aerosol constituent in nano..
