chemical equilibrium
the point where the forward reaction is running at the same rate as the reverse reaction
what is chemical equilibrium?
When a chemical reaction makes more products or reactants we like this, we say that the reaction _____s.
what is shifts?
Reaction products have a high concentration when K is ___________.
What is very large?
Reaction reactants have a high concentration when K is _____________
what is very small?
What does the pH scale measure?
what is the the acidity or basicity of a solution ?
in essence, _________ reactions are equilibrium reactions
The up sloping line represents the _______ reaction
what is reverse reaction?
When K is very large: → (point to the ______
what is to the right?
When K is very small: ← (point to the
what is point to the left?
The lower the pH number the more ____ a solution.
what is acidic?
the down sloping line represents the ______ reaction
what is forward reaction?
If a reaction has not yet reached equilibrium, it must:
make more ________
or make more _______ (which will lower the rate of the reverse reaction).
When a chemical reaction does something like this, we say that the reaction “shifts.”
what is more products
(which will lower the rate of the forward equation)
make more reactants (which will lower the rate of the reverse reaction).
_______ & _______ elemental states can be used in the equilibrium equation
what are Gaseous and aqueous?
_______ & _________ elemental states can not be substituted in the equilibrium equation- leave them out
what are Solid and liquid elemental states?
The higher the pH number the more _____a solution is.
what is basic ?
By viewing a _______ depiction of a reaction at equilibrium, we can determine
When a reaction is in equilibrium
When a reaction is not in equilibrium
How long it is in equilibrium
What is a graphic depiction?
Molarity expresses the relationship between
what is the number of moles of a solute per liters of solution, or the volume of that solution ?
LeChatelier’s Principle tells us that ....
what is When a stress is applied to an equilibrium, the reaction will shift in a way that relieves the stress and restores equilibrium?
what are some examples of stresses according to Le Chatelier's Principle?
what are change in concentration, pressure, or temperature?
The higher the pH, the weaker the acid.The weaker the acid, the _____ the ionization constant.
what is smaller?
The _________can be used to predict the direction that a chemical reaction will shift if it is not already at equilibrium.
