  • 12.2 Factors Affecting Reaction RatesChemistry

    Hence the rate of a reaction between two phases depends to a great extent on the surface contact between them. A finely divided solid has more surface area available for reaction than does one large piece of the same substance. Thus a liquid will react more rapidly with a finely divided solid than with a large piece of the same solid.

  • Factors Affecting Reaction Rates

    The surface area is the sum of the area of all six sides of the cube. The surface area of the cube can be increased by dividing the cube into smaller cubes. Surface area is maximized when a single large cube is crushed to fine powder. The rate of reaction of a solid substance is related to its surface area.

  • The Rates of Chemical Reactions

    How does surface area affect a chemical reaction If one of the reactants is a solid the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface i.e. on the surface of the solid. So the larger the surface area of the solid the

  • What Factors Affect the Rate of Reaction Between Magnesium

    Grinding up the magnesium into a powder increases the surface area so the acid has more space to react on. How does Concentration affect the rate of reaction between Magnesium and Hydrochloric acid The gas produced from the reaction will be measured and used to display the average rate of reaction. The rate of reaction is a measure of

  • Why Does an Increase in Reaction Temperature Generally

    Why Does an Increase in Reaction Temperature Generally Increase the Reaction Rate Temperature increases the reaction rate by increasing the number of collisions and making more forceful collisions. A rise in temperature is an increase of motion and energy so collisions happen more often and more violently resulting in product formation.

  • How to Dissolve Sugar Faster Sciencing

    Energy which is the capacity to do work or produce heat affects the rate at which a solute will dissolve. Breaking up crushing or grinding a sugar cube before adding it to water increases the sugar s surface area. The more surface area a solute has the faster it will dissolve because more particles of the sugar can interact with the water.
