Define the term Equilibrium Constant?

If the equilibrium constant for an equilibrium system has decreased because of a "stress", how have the concentrations changed? O [reactants] and [products] decreases [reactants] decreases and [products] increases O [reactants] increases and [products] decreases [reactants] and [products] increases

Write the pressure equilibrium constant expression for this reaction. 2 H,(g)+O,(9)→2H,0(1)

What can be said about the magnitude of the equilibrium constant in a reaction whose equilibrium lies far to the right? To the left?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. An industrial chemist studying this reaction fills a 100. L tank with 42. mol of sulfur dioxide gas and 5.6 mol of oxygen gas, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 9.0 mol. Calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. Round your answer to 2 significant digits. K_ = ] x10

Decide whether each of the following statements is true or false.  If false, change the wording of the statement to make it true.   a) The magnitude of the equilibrium constant is always independent of temperature. b) When two chemical equations are added to give a net equation, the equilibrium constant for the net equation is the product of the equilibrium constants of the summed equations. c) The equilibrium constant for a reaction has the same value as K for the reverse reaction.  d) Only the concentration of CO2 appears in the equilibrium expression for the reaction: CaCO3 (s) ↔ CaO (s) + CO2 (g). e) For the reaction CaCO3 (s) ↔ CaO (s) + CO2 (g), the value of K is numerically the same whether the amount of CO2 is expressed as molarity or as gas pressure.

What happens to the rate of the forward reaction as an equilibrium reaction proceeds

There are 5 main factors that affect the equilibrium of a chemical system.

Define equilibrium constant Keq

Suppose a 500. mL flask is filled with 0.30 mol of SO, and 1.2 mol of SO3. This reaction becomes possible: 2SO, (g) +O,(g) 2SO3 Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of O,. You can leave out the M symbol for molarity. so, SO2 O2 initial change equilibrium
