Answer #1

a) increasing the amount of water will shift the reaction towards right since water is a reactant and adding reactants shifts the equilibrium towards products.

b) Decrease the pressure by half will shift the reaction to the right side as decreasing the pressure will shift the equilibrium towards the side with the most mole of gases.

c) Remove C from the reactants will have no effect on the shift since pure liquids and solids have no effect on the equilibrium position.

d) Adding hydrogen to the mixture will shift the reaction towards left since hydrogen is a product and adding products will shift the equilibrium towards reactants.

e) Increasing the temperature will shift the equilibrium towards right because an increase in temperature favours the endothermic reaction
