Reactant concentration chang
WebNov 21, 2024 · The rate of a chemical reaction can be altered by changing the reacting conditions. There are five factors that affect the rate of a reaction: Total surface area of a solid reactant or particle size of a solid reactant Concentration of a reactant in solution Temperature of a reaction Use of catalyst WebThe reactant concentration decreases with time.-0 M ¢[H2] ¢t. 40 s. this graph individually. Change in Reactant and Product Concentrations The reactant concentration, as expected, decreases with time because reactants are consumed in a reaction. The product concentra- tion increases with time because products are formed in a reaction.
