2H2(g) + CO(g) ------------> CH3OH(g)
H = -90.2KJ
The concentration of reactants are increases or concentration of products are decreases the equilibrium shift to forward direction.
The concentration of products are increases or concentration of reactants are decreases the equilibrium shift to reverse direction.
The forward reaction is exothermic reaction. The exothermic reaction is takes place at lower temperature.
1.H2 is added .The equilibrium will shift forward direction ( product side)
2. Co is removed . The equilibrium will shift reverse direction ( reactant side)
3. CH3OH is added . The equilibrium will shift reverse direction ( reactant side)
4. The temperature of the system is increased.The equilibrium shift to reverse direction ( reactant side)
5. Catalyst is added . The equilibrium will shift ( no effect on equilibrium)
