Chemical reaction time
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. These are cal… WebThe reaction of the rusting of iron involves an increase in the oxidation state of iron, accompanied by a loss of electrons. Rust is mostly made up of two different oxides of iron that vary in the oxidation state of the iron atom. These oxides are: Iron (II) oxide or ferrous oxide. The oxidation state of iron in this compound is +2 and its ...

The rate of chemical reaction is defined as the change in concentration of a reactant or product in a given time. At the start, the rate of reaction is the fastest due to the concentration of reactants being the greatest. As the reactant proceeds, the rate of reaction slows down as the concentration decreases; the reaction stops.
