This increases the collision frequency between particles. Effect of the surface area of reactants 6.

There are four main factors that can affect the reaction rate of a chemical reaction.

. In this lesson we go through the five factors that affect the rate of a reaction. The rate of a chemical reaction depends on a few generic factors such as. Interstitial and Substitutional Alloys.

Increases and hence the rate increases. Conditions Necessary for a Chemical Reaction to occur. We show the effect of a change in each of these factors.

The concentration of the reactants 3. Intramolecular Force and Potential Energy. Increasing the concentration of one or more reactants will often increase the rate of reaction.

The rate of a reaction. Law of mass action enunciates that greater is the conc. The chemical nature of the reacting substances the state of subdivision one large lump versus many small particles of the reactants the temperature of the reactants the concentration of the reactants and the presence of a catalyst.

Variable Oxidation State of Transition Elements. The Chemical Nature of the Reacting Substances. Factors Affecting Reaction Rates.

Therefore the rate of reaction decreases as the force of attraction within the reactants increases because. Thus The higher the number of active molecules in the reactant per unit volume the faster the reaction rate. The Forces of Attraction Repulsive Forces.

However heat gain is not always the best or the most practical thing to do. Ionic and Molecular Compounds. We can identify five factors that affect the rates of chemical reactions.

There are four main factors that can affect the reaction rate of a chemical reaction. There are five factors that affect the rate of a reaction. Increasing the concentration of reactants increases the number of activated molecules per unit volume.

The temperature of the reaction 4. 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 Pressure for a reaction involving gaseous reactants. Presence of a catalyst in the reaction 5.

There are four factors that. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. These six factors which influence the rate of a reaction can be summarised as 1.

Nature of the reactants 2. State of division of a solid surface area concentration pressure of a gas temperature and catalysts. Explanation of the Factors Affecting Rate of Reaction.

The concentration of gases increases as pressure increases increasing the rate of reaction. Physical Sciences Grade 12. A catalyst changes the rate of reaction but is.

The chemical nature of the reacting substances the state of subdivision one large lump versus many small particles of the reactants the temperature of the reactants the concentration of the reactants and the presence of a catalyst. Bonding and Elemental Properties. The greater the number of successful collisions the faster the rate of a reaction.

Increasing the concentration of one or more reactants will often increase the rate of reaction. A A concentration of the reactant b Pressure in the case of gases c Temperature of reaction d Catalyst e A surface area of solid reactant. Ii Pressure Gaseous reaction.

The reaction rate accelerates in the direction of fewer gaseous molecules and slows in the opposite direction. Catalyst The rate of a reaction can be dramatically increased by supplying heat energy andor increasing the concentration of reactants. Five factors typically affecting the rates of chemical reactions will be explored in this section.

Behaviours to increase the number of activated molecules per unit volume. Experiments show that the rates of reactions are affected by several factors variables. Factors that affect the rate of reaction Chemical reaction rates increase or decrease according to factors including temperature pressure and light.

For example suppose that you want to increase the rate of a reaction such as the decomposition of glucose in a living cell. As a result it is clear that pressure and concentration are related and that they both influence the rate of response. Effect of radiation Learn Everything About Chemical Reactions.

1 Chemical Nature of the Reactants. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. Temperature of the system When we increase the temperature we are delivering more energy into the system.

This is called the collision theory. On increasing the pressure volume decreases and conc. Of the reactants the more rapidly the reaction proceeds.

FACTORS AFFECTING THE RATE OF REACTION. Therefore the reaction rate will depend on. These are called successful collisions.
