Which of these statements is/are true?
i: a reaction stops when the equilibrium is reached.
ii: an equilibrium reaction is not affectedby increasing the concentrations of products.
iii. if one starts with a higher pressure of reactant, the equilibrium constant will be larger.

The correct answer is III. If one starts with a higher pressure of reactant, the equilibrium constant will be larger.

Explanation:

I - The reaction does not stop when it reaches equilibrium. It continues to react but at a very high speed both in the direction of the reactants to the products (direct direction) and the reactants to the products (reverse direction).

II - There are 3 main factors that affect the equilibrium of a reaction:  Concentration of reactants or products; Temperature; Pressure (only gaseous reactions).

III - An increase in pressure the equilibrium will shift to the right and the yield will increase
