Rates And Equilibria Flashcards
1
Q
State Le Chatelier’s principle
2 Marks
A
- When the conditions on a system in equilibrium are changed the equilibrium moves to minimise the effects of the change/ counteract/ oppose the change
2
Q
Give two features of a reversible reaction, when a dynamic equilibrium has been
set up.
A
- rate of forward reaction = rate reverse reaction
- closed system needed
- macroscopic properties remain constant/ concentrations remain constant (?)
3
Q
Catalyst definition
A
A substance that provides an alternative reaction pathway with a a lower activation energy
- the catalyst is not used up or chemically changed during the reaction
4
Q
Effect of increased temperature on rate of reaction using Boltzmann distribution graphs
A
Jsjsm
5
Q
Conditions of reaction in the Huber process
A
Pressure - 50 - 1000atm
Temperature: 200 - 600 Degrees
