Write in short factors affecting rate of reaction
Answers
Explanation:
Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.
Answer:
1) Concentration of reactants: Reactions occur with great speed when concentration of reactants is high, and vice-versa.
2) Temperature: It also influences the rate of reaction. Reactions occur with greater speed at higher temperature. Speed of a reaction almost doubles for every 10K increase in temperature.
3) Catalyst: A catalyst alters the speed of reaction. It helps to attain equilibrium quickly. It participates in a reaction without forming any products.
4) Surface area of the reactants: Smaller the particle size, greater the surface area and faster is the reaction. So, powdered form of catalyst is better catalyst.
5) Nature of reactants and products: Rates of reactions are influenced by the nature of reactants and products. The reactivity of a substance depends on the ease with which the bonds are broken or formed.
