Factors Affecting the Rate of CR

• Reaction kinetics - is the study of the rate of chemical reactions, and reaction rates can vary greatly over a large range of time scales.
• Activation Energy - The minimum energy required to bring about a chemical reaction
• Effect of Surface Area - When solids take part in chemical reactions, only the surface particles are exposed, so they are the only ones that can collide with particles of other reactants.
• Larger surface area = faster reaction
• Gas Reactions - The rate of reaction between gases is increased by increased pressure.
• Higher pressure = faster reaction
• Effect of Temperature - As the temperature increases the number of collisions increases as well as the energy of the collisions.
• Higher temperature = faster reaction
• For every 100C increase the rate approximately doubles.
• catalyst - is a substance that increases the speed of a reaction without being used up.
• catalyst can be "recovered at the end of a reaction and used again."
