The idea that if you change the conditions of a revrsible reaction at equilibrium , the system will try to counteract that change - Can be used to predict the effect of any changes you make to a reaction system.
1 of 6
Equilibrium
A state in which opposing forces or influences are balanced.
2 of 6
Rate of reaction is dependent on :
Temperature , The concentration of a solution or the pressure of gas , Surface area , Presence of a catalyst.
3 of 6
Rate of a reaction =
Amount of reactant used or amount of produce formed - ( Divided by ) Time
4 of 6
Measuring rates of reaction -
Precipitation and colour change , Change in mass ( Often gas given off ) , The volume of gas given off
5 of 6
Ploymers
long chains of repeating units, Intermolecular forces between polymer molecules are larger than between simple covalent molecules - so more energy is needed to break them , The intermolecular forces are still weaker than ionic or covalent bonds
