Select all of the true statements below. Group of answer choices Chemical reactions shift left or right to run away from the applied stress. Equilibrium theory is concerned with the flow of energy. Equilibrium theory can answer the question: "what is the extent to which the reaction happened?" Equilibrium theory can answer the question: "how fast does the reaction happen?" The equilibrium constant is given the symbol .

Suppose you have two identical unopened bottles of carbonated beverage. The contents of both bottles appear to be perfectly clear. You loosen the cap of one of the bottles and hear a hiss as gas escapes, and at the same time gas bubbles appear in the liquid. The liquid in the unopened bottle still appears to be perfectly clear. Explain these observations using the concept of equilibrium and Le Chteliers principle. Remember, a carbonated beverage contains carbon dioxide gas dissolved in a liquid under pressure.

. What does it mean to say that a state of chemical or physical equilibrium is dynamic?

Consider the following equilibrium system. N2(g)+O2(g)2NO(g) a. Write the chemical equation for the forward reaction. b. Write the chemical equation for the reverse reaction.
