The equilibrium constant, Kp, for the following reaction is 0.215 at 673K : NH4I(s)NH3(g)+HI(g) Calculate the partial pressure of each gas and the total pressure at equilibrium when 0.546 moles of NH4I(s) is introduced into a 1.00L vessel at 673K. Assume that the volume occupied by the solid is negligible. PNH3=PHI=Ptotal=atmatmatm
