Example Question #1 :Help With Reaction Quotient
Consider the following balanced reaction:
The solution has the following concentrations:
Based on these concentrations, what will happen to the solution?
It will shift to the left
The system is at equilibrium
More information is needed in order to answer the question
It will shift to the right
It will shift to the left
By placing these initial concentrations in the equilibrium expression, we can compare the reaction quotient,
The reaction quotient for this reaction is:
Note that the reactant is a pure solid, and will not be included in this expression. By setting this equal to the equilibrium constant, we can see whether
We can predict how a solution will change based on the value of
Since the value for
Example Question #56 :Reactions And Equilibrium
Consider the following reaction.
What is the reaction quotient if
没有t enough information to answer this question
The reaction quotient, or Q, of the above reaction is equal to the products over the reactants. Q is calculated in the same manner as Keq, but does not require that the reaction be at equilibrium.
