Question

State 4 factors affecting the rate of chemical reaction.​

Answer 1

Answer:-1.Reactant concentration

2.physical state of the reactants

3.surface area

4.The presence of a catalyst

:-increasing the concentration of reactants will increases the rate of reaction.increasing the concentration of the reactants will also increases frequency of collisions  of reactants

:-a chemical reaction between substances require contact between the two reactants

:- if the surface area of a reactant increases. more particles are exposed to the reactant

:-catalyst are substances that increase reaction rate. the main role of a catalyst is to lower the activation energy so the large amount of particles are sufficient energy to react.

Answer 2

:-Increasing the concentration of reactants accelerates the reaction rate.

As the concentration of reactants rises, the frequency of reactant collisions rises as well.

:-A chemical reaction involving two reactants necessitates contact between them.

:- if a reactant's surface area grows. The reactant is exposed to a greater number of particles.

Catalysts are compounds that speed up the pace of a process. The primary function of a catalyst is to reduce the activation energy so that a large number of particles have enough energy to react.

following are the factors which affecting the rate of chemical reaction.​

1.Composition of the reactant

2.the status of the reactants in terms of their physical properties

3.the area of the surface

4.Availability of a catalyst
