RATE OF REACTION

• WHAT IS RATE OF REACTION?

  change in concentration of reactants or products with unit of time
• HOW TO FIND RATE OF REACTION AT A PARTICULAR INSTANCE?

  draw tangent -> change in concentration / time
• WHAT IS RATE EXPRESSION?

  equation describing how rate of reaction at a particular temperature depends on concentration of species involved
• WHAT IS THE RATE CONSTANT?

  k
• WHAT IS k AFFECTED BY?

  temperature
• ZERO ORDER?

  if concentration changes, rate does not change
• FIRST ORDER?

  if concentration doubles, rate will double (etc.)
• SECOND ORDER?

  if concentration doubles, rate will increase by a factor of 4 (etc.)
• GRAPH OF A ZERO ORDER?

  horizontal straight line
• GRAPH OF A FIRST ORDER?

  diagonal straight line
• GRAPH OF AN ORDER GREATER THAN ONE?

  curve
