Rate Equations

AQA Content

###### Use concentration-time graphs to deduce the rate of a reaction

###### Use initial concentration-time data to deduce the initial rate of a reaction

###### Use rateâ€“concentration data or graphs to deduce the order (0, 1 or 2) with respect to a reactant

###### Derive the rate equation for a reaction from the orders with respect to each of the reactants

###### Use the orders with respect to reactants to provide information about the rate-determining/limiting step of a reaction.

Specification Notes

###### The rate equation is an experimentally determined relationship.

###### The orders with respect to reactants can provide information about the mechanism of a reaction.
