A1: Equilibria Flashcards
1
Q
When does dynamic equilibrium exist?
A
In a closed system, when the rate of forwards reaction=rate of backwards reaction, and the concentration of the products and reactants doesn’t change
2
Q
Le Chatlier’s principle
A
When a system in equilibrium is subjected to an external change position of equilibrium shifts to minimise this change
3
Q
Ideal conditions for the Haber Process
A
Temperature: 350-500 degrees C, compromise between yield and high rate
Pressure: 100-200 atm increases yield and rate, but isn’t dangerously high

Q
Kc expression
A
[Products]/[reactants]
