Which of the following is correct for .

(1) As time passes by [N2] , [H2] decreases and [NH3] increases and at equilibrium concentrations of both reactants and products remain unchanged with time.This  graph, [NH3] is decreasing and [N2] & [H2] are increasing hence,it's not a correct representation. (2)This is a correct representation. As time passes by [N2],[H2] decreases, and [NH3] increases and at equilibrium concentrations of both reactants and products remain unchanged with time. (3)In this graph [NH3], [N2] & [H2] are decreasing, this is impossible.
