Chemical Kinetics

• Study of reaction rates; how they change with varying conditions or which molecular events occur during overall reaction. chemical kinetics
• Variables affecting the rate of reaction:

  Concentrations of the reactant
• Variables affecting the rate of reaction:

  concentrations of the catalyst
• Variables affecting the rate of reaction:

  temperature at which the reaction occurs
• Variables affecting the rate of reaction:

  surface area of the solid reactant/catalyst
• REACTION RATE

  increase in molar concentration of product of a reaction per unit time
• REACTION RATE

  decrease in molar concentration of reactant of a reaction per unit time
• An increase in the rate of reaction resulted from the addition of a catalyst. catalysis
• popular example of a catalyst (biological). enzymes
• TYPES OF CATALYSIS:

  uses the catalyst in the same phase as the reacting species. Homogenous Catalysis
• TYPES OF CATALYSIS:

  uses catalyst in a different phase from the reacting species/ Heterogenous Catalysis
• TYPES OF CATALYSIS:

  binding of a species to the surface by chemical bonding forces that break the bonds in the species. Chemisorption
• TYPES OF CATALYSIS:

  enormous catalytic activity, highly specific, substance is referred as substrate. Enzyme Catalysis
