Question

How does the rate of reaction depend upon the concentration of the
reactants? Give suitable example.​

Answer 1

Explanation:

1) A chemical reaction takes place due to collisions of the reactant molecules. Higher the concentrations of the reactants more will be the frequency of collisions and faster will be the rate of the reaction. <br> (2) In the reaction of dil. HCI and

disappears slowly and

also liberates slowly. On the other hand th reaction with concnetrated HCI takes place rapidly and

disappears fast. <br> (3) Concentrated acid reacts faster than dilute acid, that means the rate of a reaction is proportional to the concentration of reactants. <br> Slow reaction. <br>

<br> Fast reaction : <br>
