The speed at which reactions take place is studied by reaction kinetics. The rate depends on various parameters, such as: • Reactant concentrations, which usually make the reaction happen at a faster rate if raised through increased collisions per unit of time. Some reactions, however, have rates that are independent of reactant concentrations, due to a limited number of catalytic sites.
