At 1400 K, Kc= 2.5x10+3 for the reaction CH4(g) + 2H2S(g) $\underset{}{\overset{}{⇌}}$ CS2(g) + 4H2(g). A 10.0L reaction vesselat 1400 K contains 2.00 mole of CH4, 3.0 mol of CS2, 3.0 mole of H2 and 4.0 mole of H2S. Then

(1) This reaction, is at equilibrium with above concentrations.

(2) The reaction will proceed in forward direction to reach equilibrium.

(3) The reaction will proceed in backward direction to reach equilibrium.

(4) The information is insufficient to decide the direction of progress of reaction.
