For HI(g) heated to 500 C in a 1.00 L reaction vessel, chemical analysis determined these concentrations at equilibrium: [H,1 = 0.427 M. [121 = 0.427 M. and [HI] = 3.61 M. If an additional 1.00 mol of HI(g) is introduced into the reaction vessel. what are the equilibrium concentrations after the new equilibrium has been reached? [HD] = M [H.] = M M
