What does Le Chatelier's principle state

A reaction at equilibrium will respond to balance a change - apex

(Explanation): The answer is NOT "a new equilibrium ratio will form", because although this is true, it will not necessarily always happen and is not what le chatelier's principle is about. His principle focuses on the reaction changing to cancel out or balance the change in equilibrium. Therefore, this is the correct answer.

Does a large equilibrium constant mean that the reaction must be rapid

No! The equilibrium constant is thermodynamic. Reaction rate is kinetic.

What is salt neutralization

Salts are the products of reactions between acids an bases (neutralization reactions).

How would a drop in pressure affect a gaseous system at equilibrium

the reaction would shift to favor the side with the most moles of gas. (apex).

Which describes two phases in dynamic equilibrium

the total number of molecules in each phase stays constant

What would be the pH of a neutral solution An acid solution A basic solution

Neutral solution: pH =7
Acidic solution: pH<7.
Basic solution: pH>7.

What is the triple point on a phase diagram Apex

a point indicating three phases in dynamic equilibrium
