Reversible Reactions Flashcards
1
Q
Define dynamic equilibrium
A
When the rate of forward reaction and backward reaction remains constant, so that the concentration of products and reactants remains constant.
2
Q
How can the dynamic equilibrium be altered in a reversible reaction?
A
Changing:
- concentration
- temperature
- pressure
3
Q
What is Le Chatelier’s Principle?
A
If the conditions of a system in dynamic equilibrium is altered, the system will move to oppose the change.
4
Q
Optimum reaction conditions for Haber’s Process
A
Temperature: 450-500 degrees
Pressure: 250 atmospheres
Catalyst: finely divided iron
5
Q
Define reversible reaction
A
A reaction that may move either forwards or backwards.
