Equilibrium Flashcards
(7 cards)
1
Q
what is the only external factor that affects value of Kc
A
Temperature
2
Q
How do you calculate Kc
A
ICE chart
Initial Moles, Reacting Moles and Equilibrium moles
3
Q
What is the values for reactants and products in an ICE chart
A
Reactants = -x
Products= +x
4
Q
when can Kc be calculated using moles instead of concentration
A
if there is no units
5
Q
Kc equation
A
Kc= sum of [products]
sum of [reactants]
6
Q
what does % dissociation mean
A
% of mol reacting
7
Q
Changes that affect rate at which equilibrium is established
A
-incr temp speeds up forward and backwrd
-eq attained faster if incr pressure of homogenous gaseous equilibrium or add catalyst
-if position shift left - backward reaction sped up more than forward due to external factor
