... the ideal gas law, PV = nRT. A theory (model) is an attempt to explain why something happens. Dalton’s atomic theory explains why mass is conserved in a chemical reaction. The kinetic molecular theory explains why pressure and volume are inversely related at constant temperature and moles of gas pre ...

... The best way to identify a redox reaction is to assign oxidation states to all elements in the reaction. If elements show a change in oxidation states when going from reactants to products, then the reaction is a redox reaction. No change in oxidation states indicates the reaction is not a redox rea ...

Catalysis



Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
