C3-Bond Energies
- Exothermic - the reactants on a graph are higher than the products formed.
- Endothermic- the reactants on a graph are lower than the products formed.
- Activation energy is lowered by catalysts.
- Activation energy
represents the minimum
energy needed by
reacting particles to
break their bonds.
- A catalyst provides a different
pathway for a reaction that
has a lower activation energy (
so the reaction happens more
easily and quicker.
- The overall energy change for the
reaction remains the same though.
- Activation energy
represents the minimum
energy needed by
reacting particles to
break their bonds.
- On a graph, if a catalyst has been added, the activation energy will be lower
than without one and the reaction will be over quicker.
