What effect do the listed changes have on the position of the equilibrium in the reaction of carbon with hydrogen?C(s) + 2 H2(g) ⇌ CH4(g) ∆H = -18 kcal/mol (-75kJ/mol)Increasing pressure by decreasing volume

What effect do the listed changes have on the position of the equilibrium in the reaction of carbon with hydrogen?C(s) + 2 H2(g) ⇌ CH4(g) ∆H = -18 kcal/mol (-75kJ/mol)Allowing CH4 to escape continuously from the reaction vessel

Why do catalysts not alter the amounts of reactants and products present at equilibrium?

When the following equilibria are disturbed by increasing the pressure, does the concentration of reaction products increase, decrease, or remain the same?2 CO2(g) ⇌ 2 CO(g) + O2(g)

The reaction CO(g) + H2O(g) ⇌ CO2(g) + H2(g) has ∆H = -9.8 kcal/mol (-41 kJ/mol). Does the amount of H2 in an equilibrium mixture increase or decrease when the temperature is decreased?

The reaction H2(g) + I2(g) ⇌ 2 HI(g) has ∆H = -2.2 kcal/mol (-9.2 kJ/mol). Will the equilibrium concentration of HI increase or decrease whenA catalyst is added?

The reaction H2(g) + I2(g) ⇌ 2 HI(g) has ∆H = -2.2 kcal/mol (-9.2 kJ/mol). Will the equilibrium concentration of HI increase or decrease whenH2 is removed?

The reaction Fe 3+(aq) + Cl -(aq) ⇌ FeCl 2+(aq) is endothermic. How will the equilibrium concentration of FeCl 2+ change whenCl - is precipitated by addition of AgNO3?
