- Collision TheoryFor a reaction to occur, the particles that are reacting must be moving with enough kinetic energy to collide with enough energy for existing bonds…
- Factors Affecting Rate of ReactionIncreasing the pressure of a gas.
- Activation EnergyFor a chemical reaction to occur, the bonds within the reactants must be broken and new bonds must be formed between the atoms to make the products.
- Exothermic ReactionsThe reaction profile diagram for an exothermic reaction shows the enthalpy change and activation energy.
- Endothermic ReactionsThe reaction profile diagram for an endothermic reaction shows the enthalpy change and activation energy.
- Maxwell-Boltzmann DistributionAt any given temperature, molecules have a range of speeds and energies.
- Maxwell-Boltzmann Distribution and Activation EnergyFor a chemical reaction to occur, the bonds within the reactants must be broken and new bonds must be formed between the atoms to make the products.
- The Effect of Temperature on Reaction RateThe Maxwell-Boltzmann distribution curve show the distribution of energy of the particles.
- CatalystsCatalysts are substances that speed up chemical reaction without themselves being chemically changed.
- Catalytic ConvertersCars have catalytic converters fitted to their exhaust pipes.
