How Does Surface Area Affect The Rate Of Reaction

How Does Surface Area Affect The Rate Of Reaction. The surface area of a catalyst most certainly does affect the rate of reaction. We know this because the line for the larger surface area has a steeper gradient and it becomes horizontal faster.

Rate of reaction chemical (condensed) from www.slideshare.net

In chemical reactions, in which a solid reactant is present, the surface area of this reactant also affects the reaction rates. 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. Surface area may seem like it has absolutely no affect on how fast or slow reaction rate can occur but you are wrong!

When the temperature of a reaction increases, the rate of reaction increases. Factors that affect reaction rates include the concentrations of the reactants, the nature of the reactants, temperature, and the presence or absence of a catalyst or inhibitor.

The reason for that is simple. The line for the greater surface area (powdered reactant) shows a higher rate of reaction than the smaller surface area.

The results of the experiment describe how the surface area of a reactant (the chalk) speeds up the rate of reaction when in contact with another reactant in this instance, the hydrochloric acid. The greater the surface area, the faster the sugar will dissolve.

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. The greater the surface area, the faster the sugar will dissolve.

An example of a fast reaction rate using surface area is sugar dissolving in a hot beverage. When the temperature of a reaction increases, the rate of reaction increases.

For A Chemical Reaction To Occur Three Conditions Must Be Achieved (At The Most Basic Level).

When reactants can bump into each other more quickly, they will react more quickly. Follow me on instagram @chem.jungle for quizzes, notes and. It includes cases where the solid is acting as a catalyst.

Surface Area Is One Of The Factors That Affect The Rate Of Reaction.

Effect of surface area on rate. Chemical reactions involving a catalyst occur on the surface of the catalyst and the catalyst works by lowering the activation energy of the reaction. Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid.

This Can Be Explained Using The Collision Theory, As Below.

This applies to reactions involving a solid and a gas, or a solid and a liquid. If you have a reaction between a solid and a liquid or a gas, the reaction is normally faster if the solid is finely divided. Therefore there are more particles of.

Explain Why The Results Were The Way They Were.

The results of the experiment describe how the surface area of a reactant (the chalk) speeds up the rate of reaction when in contact with another reactant in this instance, the hydrochloric acid. Explain to your students that in the. This is done by cutting the substance into small pieces, or by.

Factors That Affect Reaction Rates Include The Concentrations Of The Reactants, The Nature Of The Reactants, Temperature, And The Presence Or Absence Of A Catalyst Or Inhibitor.

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This video explains how surface area affects the rate of reaction. The more finely divided the.
