F325 rates

The time taken for the concentration of a reactant to reduce by half.
The power to which the concentration of the reactant is raised in the rate equation.
Overall order
The sum of the individual orders: m + n.
Rate constant, k
The constant that links the rate of reaction with the concentrations of the reactants raised to the powers of their orders in the rate equation.
Rate equation
For a reaction: A + B > C, the rate equation is given by:
Rate of reaction
The change in concentration of a reactant or a product in a given time.
Rate-determining step
The slowest step in the reaction mechanism of a multi-step reaction.
The molar relationship between the relative quantities of substances taking part in a reaction.
