9 Equilibria Flashcards
1
Q
Reaction at dynamic equilibrium means:
A
- forward and reverse reactions proceed at equal rates
Simultaneously - the concentrations of reactants and products remain constant.
2
Q
Equation for Kc
A
For: A+ B –> C + 2D
Kc = [C] [D]^2 / [A] [B]
[products]/[reactants]
0 (reactants) -1 (equilibrium) -1+ (products)
2
Q
Effect of catalyst on equilibrium
A
A catalyst does not affect the position of equilibrium.
2
Q
Le Chatelier’s principle.
A
If an external condition to an equilibrium is changed, the equilibrium will shift to oppose the change
2
Q
How does the value of Kc change with changes in concentration or addition of a catalyst?
A
No change
