Factors Affecting the Rate of Reaction.

. Effect of the surface area of reactants 6. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How YouTube works Test new features Press Copyright Contact us Creators. Conditions Necessary for a Chemical Reaction to occur.

The Forces of Attraction Repulsive Forces. 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. Experiments show that the rates of reactions are affected by several factors variables.

The rate of a reaction is affected by the following factors. What are the six factors that affect the rate of reaction. High concentration of reactants leads to more effective collisions per unit time which increases reaction time.

A substance that is concentrated has more molecules particles for a given. In general something that increases the number of collisions between particles will increase the reaction rate. - higher the temp faster the rate as more successful collisions are happening as particles have more energy.

The difference in rates of reaction is caused by several factors such as Concentration of Reactants Temperat. Factors Affecting the Reaction Rate. An acidic oxide sulfur dioxide combines with water vapor in the air to produce sulfurous acid in the following reaction.

This video covers- Collision theory and how it relates to the rate of reaction- The effect of temperature- The effect of concentration and pressure- The ef. This is called the collision theory. A A concentration of the.

Explanation of the Factors Affecting Rate of Reaction. For each factor that increases the rate of reaction doing the opposite will decrease it. These six factors which influence the rate of a reaction can be summarised as 1.

SO 2 g H 2 O g H 2 SO 3 a q Calcium carbonate reacts with sulfurous acid as follows. High concentrationmore collisions. The rates at which reactants are consumed and products are formed during chemical reactions vary greatly.

Chemical Reactions proceeds at different rates. Depending on the fastness or slowness of the reaction. Therefore the reaction rate will depend on.

The rate of this reaction depends on the amount of sulfur dioxide in the air Figure 127. 1 Chemical Nature of the Reactants. Nature of the reactants 2.

Factors Affecting Reaction Rates - Key takeaways Rate of reaction is a measure of either how quickly reactants are used up or how quickly products are formed in a chemical reaction. There are four factors that affect the rate speed of a chemical reaction. Use of a catalyst.

The temperature of the reaction 4. CaCO 3 s H 2 SO 3 a q CaSO. Presence of a catalyst in the reaction 5.

However significant changes in the reaction can be. So far we have learnt that rate of reaction can be increased to certain extent by increasing the concentration temperature and surface area of the reactant. Therefore the rate of reaction decreases as the force of attraction within the reactants increases.

In other words it is the change in concentration of reactants or products over time. The rate of a reaction depends upon how frequently the moleculesparticles of the reacting substances collide. Rate of reaction depends on four things.

The concentration of the reactants 3. We can identify five factors that affect the rates of chemical reactions. Factors Affecting Reaction Rates.

Temperature concentration or pressure of gas catalyst surface area. 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. Nature and State of the Reactant.

The unit of the rate is usually expressed as mol L -1 s -1 or min -1 h -1 etc.
