C3- Reversible reactions
- Is one where the products of the reaction can themselves react to produce the
original reactants
- If it takes place in a closed system ( none of the reactants/products can
escape) then a state of equilibrium will always be reached.
- Equilibrium - the amount of reactants and products will reach a certain
balance and stay there
- Equilibrium - the amount of reactants and products will reach a certain
balance and stay there
- If it takes place in a closed system ( none of the reactants/products can
escape) then a state of equilibrium will always be reached.
- The position of equilibrium depends very strongly on the temp and pressure surrounding the reaction.
- If you deliberately alter one of these, you can move the position of equilibrium to give more product and less reactants.
- If you deliberately alter one of these, you can move the position of equilibrium to give more product and less reactants.
- All reactants and exothermic in one direction and endothermic in the other
- If you raise the temperature, the endothermic reaction will increase to use up
the extra heat
- If you reduce the temperature, the exothermic reaction will increase to give out
more heat.
- If you reduce the temperature, the exothermic reaction will increase to give out
more heat.
- If you raise the temperature, the endothermic reaction will increase to use up
the extra heat
- If you raise the pressure, it will encourage the reaction which produces less volume.
- If you lower the pressure, it encourages the reaction which produces more volume
- If you lower the pressure, it encourages the reaction which produces more volume
