Rate of Reaction Factors
Activation Energy Ea Is the minimum EK 3 Concentration of the reactants As the concentration molL of the reactants decreases As the slope of the reactant concentration curve decreases 4 Effect of Temperature. Factors Affecting the Rate of Reaction.

Rate of a chemical reaction is the change in concentration of a reactant or product per unit time.
. This is particularly important when it comes to industrial reactions where greater productivity leads. Nature of the reaction. This chemistry video tutorial discusses five factors affecting the rate of a reaction.
There are five factors that affect the rate of a reaction. It is important to know these factors so that reaction rates can be controlled. The rate of a reaction according to the general definition is the rate at which a reaction occurs.
We can identify five factors that affect the rates of chemical reactions. 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. The nature of the reaction concentration strain reaction order temperature solvent electromagnetic radiation catalyst isotopes surface area stirring and the diffusion limit are all factors that affect the reaction rate.
This includes the nature of the reactants concentration surface are. Factors Affecting The Rate Of Reaction. 3 Factors influencing the Rate of Reaction 31 1 The Nature of the Reactants 32 2 The Concentration of the Reactants 33 3 The Temperature of the Reactants 34 4 The Presence of a Catalyst 4 A Solved Question for You Suggested Videos Rate of Reaction.
Factors Affecting Rate of Reaction. Reaction rates can vary dramatically. Temperature concentration particle size use of a catalyst 1 2 3 4 5 6 7 8 9.
The occurrence of. This is called the collision theory. Nature of the reactants.
The orientation of the molecules at collision p755 B. Factors that affect rate of reaction are. 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.
As we know some chemical reactions are naturally faster and some are naturally slower. Factors Affecting Rate of Reaction. The rates at which reactants are consumed and products are formed during chemical reactions vary greatly.
The reaction rate mainly depends on the physical state of reactants number of reactants complexity of reaction and other factors. Factors affecting reaction rates ESCN2 Several factors affect the average rate of a reaction. Presenceabsence of a catalyst.
There are four factors that affect the rate speed of a chemical reaction. There are two basic reasons for the lack of reactions. Concentration or pressure of a reactant.
Factors Affecting Reaction Rates Free Energy Free Energy of Dissolution Fundamental Particles Ground State Half Equations Heating Curve for Water Hess Law Hybrid Orbitals Ideal Gas Law Ideal and Real Gases Intermolecular Forces Ionic Bonding Ionic Product of Water Ionic Solids Ionisation Energy Ions. Some reactions occur more quickly than others. Surface area of a solid reactant.
Following are the main factors that affect the reaction rate. Wood combustion for example has a high reaction rate because the process is fast whereas iron rusting has a low reaction rate since the process is sluggish. The nature of the reaction the concentration the strain the order of the reactions the temperature the solvent the electromagnetic radiation the catalyst the isotopes the surface area the stirring and the diffusion limit are all factors that influence the rate of the reaction.
