LC chemistry rate of reactions

the change in concentration per unit time of any one reactant/product

The rate of reaction at any one particular time during the reaction

and calculated using the slope

• The nature of the reactants
• Particle size
• concentration
• temperature
• Presence of a catalyst

A substance that alters the rate of a chemical reaction but is not consumed in the reaction

A substance that is produced by a living cell and acts as a biological catalyst

a catalysis in which both the reactants and the catalyst are in the same phase

there is no boundary between the reactacts and the catalyst

Catalysis in which the reactants and the catalyst are in different phases.

there is a boundary between the reactants and the catalyst

A catalysis in which one of the products of the reaction acts as a catalyst for the reaction

A substance is drawn down onto the surface of a solid

• Platinum
• Palladium
• Rhodium

catalyze the conversion of a vehicle's pollutant exhaust gases into less harmful substances that are safer to release

The minimum energy which colliding particles must-have for a reaction to occur

the minimum energy required for the effective collision between particles to occur
