Chemical Equilibria Flashcards
1
Q
what does dynamic equilibrium mean?
A
where the forwards rate of an equation is equal to the backwards rate in a closed system where the concentration reams constant
2
Q
what is Le Chatelier’s principle?
A
equilibrium will shift to oppose the change on a system
3
Q
what are the 3 factors that affect the position of equilibrium?
A
- Concentration
- Pressure
- Temperature
4
Q
what effect does a catalyst have on the position of equilibrium?
A
- no effect
- the catalyst increases the rate of both forward and backwards reactions at the same time
5
Q
what is homogeneous equilibrium?
A
a system in which the reactants and products are in the same phase
6
Q
how do you calculate K꜀ (equilibrium constant)
A
K꜀ = [products]ᵃ / [reactants]ᵇ
a and b = the number of moles of the species which appear in the balanced equation for equilibrium
7
Q
What factor is K꜀ affected by
A
Temperature
8
