How does mass affect rate of reaction
WebIf one of the factors is halved, the volume produced will be half as much. If the factor is doubled, the reaction will produce double the volume. This applies to all factors that can … WebThe rates of many reactions depend on the concentrations of the reactants. Rates usually increase when the concentration of one or more of the reactants increases. For example, calcium carbonate (CaCO 3) deteriorates as a result of …
