  • Rate Constant
    A proportionality factor in rate equations whose units depend on the overall reaction order.
  • Reaction Order
    A classification indicating how the rate depends on reactant concentrations, affecting the units of the rate constant.
  • Zero Order
    A reaction type where the rate is independent of reactant concentration, with rate constant units of molarity per second.
  • First Order
    A reaction type where the rate is directly proportional to one reactant, with rate constant units of inverse seconds.
  • Second Order
    A reaction type where the rate depends on two reactants or the square of one, with rate constant units of inverse molarity times seconds.
  • Molarity
    A concentration unit representing moles of solute per liter of solution, used in rate constant units.
  • Inverse Seconds
    A unit indicating per second, commonly found in rate constant units for first and higher order reactions.
  • Inverse Molarity
    A unit representing per molarity, used in rate constant units for second order reactions.
  • Exponent
    A mathematical value indicating the power to which a unit is raised, used to determine reaction order from rate constant units.
  • Rate Equation
    A mathematical expression relating reaction rate to reactant concentrations and the rate constant.
  • Kinetics
    A field studying reaction rates and mechanisms, where rate constant units are essential for analysis.
  • Table
    A structured format used to compare reaction orders and corresponding rate constant units.
  • Unit
    A standard measurement used to express the magnitude of the rate constant, varying with reaction order.
