RoR

• Catalysts:

  • Provide and alternative reaction route with a lower activation energy
  • Increase the rate of reaction
• Half-life

  The time taken for the reactant concentration to half
• Order of Reaction

  The power to which the concentration of a reactant is raised in the rate equation.
• Sum of orders

  The sum of the individual orders of reactants and catalysts in the rate equation.
• Rate constant

  A constant that links the rate of reaction with the concentrations of the reactants and catalysts raised to the powers on their orders in the rate equation.
• Rate-determining step

  The slowest step in the reaction mechanism of a multi-step reaction.
• Rate of reaction

  The change in concentration of a substance in unit time.
