Chemical Equilibrium Flashcards
(22 cards)
Large K
Favors the forward reaction with a high concentration of products
Small K
Favors the reverse reaction with a high concentration of reactants
What will the reaction favor and shift if Q < K
The reaction favors products & shifts forward
What will the reaction favor and shift if Q > K
The reaction favors reactants & shifts in reverse
If there is a -ΔGrxn then is Q greater or less than K?
Q < K
If there is a +ΔGrxn then is Q greater or less than K?
Q > K
More reactants added means more or less product forms?
More Product forms
More products added means more or less reactant forms?
More Reactant forms
Removing Product means more or less product forms?
More Product forms
If pressure increases, where will the reaction shift?
On the side with fewer gas molecules
Partial pressure when moles equal on both sides means
It does not increase or decrease
Which way would a reaction shift if there is an increase in temperature
Reaction moves to the left
Which way will the reaction shift with a decrease in temperature
Reaction moves to the right
When entropy is higher within mixtures, does it result in a lower or higher ΔG?
In lower free energy (ΔG)
At chemical equilibrium
The concentrations of reactants/products are not changing
Systems always move to Equilibrium
True or False
True
Q is calculated by moles.
True/False
False
Q is calculated by concentration (M)
Decreasing the volume causes the reaction to shift
In the direction with the fewest moles of gas particles
Increasing the volume causes the reaction to shift
In the direction that has the greatest number of moles of gas particles
When temperature increases in an exothermic chemical reaction (where heat is a product), the reaction shifts
Left
When temperature increases in an endothermic chemical reaction (where heat is a reactant), the reaction shifts
Right
If pressure decreases, where will the reaction shift?
On the side with more gas molecules
