Explain the effect of concentration on the rate of reaction? Effect of concentration on the rate of reaction:When the concentration of a reactant increases, the rate of reaction also increases. (a) For example, two sets of experiments are carried out using the reacting conditions below: Set I: 1 g of zinc powder and 20 cm3 of 0.4 mol dm-3 hydrochloric acid … [Read more...] about Explain the effect of concentration on the rate of reaction?
Factors that Affect the Rate of Reactions
What is the effect of a catalyst on the rate of a reaction?
What is the effect of a catalyst on the rate of a reaction? Effect of catalyst on the rate of reaction:A catalyst is a substance which can alter the rate of a chemical reaction while itself remains chemically unchanged at the end of the reaction. (a) Catalysts can be classified into positive catalysts and negative catalysts (inhibitors). (b) A positive … [Read more...] about What is the effect of a catalyst on the rate of a reaction?
What factors affect the rate of a reaction?
What factors affect the rate of a reaction? Factors Affecting the Rate of Reaction: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 … [Read more...] about What factors affect the rate of a reaction?
How does the temperature affect the rate of a chemical reaction?
How does the temperature affect the rate of a chemical reaction? Effect of temperature on the rate of reaction:When the temperature increases, the rate of reaction also increases. (a) For example, two sets of experiments are carried out using the reacting conditions below: Set I: 1 g of granulated zinc and 20 cm3 of 0.2 mol dm-3 hydrochloric acid at … [Read more...] about How does the temperature affect the rate of a chemical reaction?
How does the surface area affect the rate of reaction?
How does the size of particles affect the rate of reaction? Effect of surface area on the rate of reaction:When the particle size of a fixed mass of a solid reactant becomes smaller, the total exposed surface area becomes larger, the rate of reaction increases.For example, two sets of experiments are carried out using the reacting conditions below: Set I: 1 g of … [Read more...] about How does the surface area affect the rate of reaction?
