At 1400 K, K_c=2.5xx10^(-3) for the reaction CH_4(g)+2H_2S(g)hArrCS_2(g)+4H_2(g).A 10.0 L reaction vessel at 1400 K contains 2.00 mole of CH_4.3.0 mole of CS_2,3.0 mole of H_2 and 4.0 mole of H_2S.Then

Answer»

This reaction is at equilibrium with above concentrations
The reaction will PROCEED in forward DIRECTION to reach equilibrium
The reaction will proceed in backward direction to reach equilibrium
The information is insufficient to DECIDE the direction of PROGRESS of reaction

Solution :`Q_c=((3/10)^4(3/10))/((2/10)(4/10)^2)=243/32xx10^(-2)=7.59xx10^(-2)gtK_c`
So, reaction will proceed in backward direction
