Equilibrium Flashcards
1
Q
What is the range for Kc values?
A
Never negative 0-1
The closer to 1- the closer they go to completion
The further from 1- the reaction hardly occurs at all
2
Q
Why would catalysts be used in equilibrium?
A
Speed up the forward and reverse equally
Aim is to produce the highest possible yield in the shortest amount of time
3
Q
What is the Liquid Vapor law?
A
Rate of vaporization=rate of condensation
4
Q
Vaporization?
A
Endothermic process
The stronger the forces the higher the enthalpy of vaporization the higher the b.p
5
Q
Vapor pressure?
A
Substances with high b.p the vapor pressure will be lower as fewer molecules will escape from the liquid phase
-exponential increase v.p w/ temp.
6
Q
What is the only thing that can change the the value of Kc?
A
Temperature!!
