Explain how concentration can affect the rate of a chemical reaction. Give an example.

Sagot :

Rate of reaction proportional to the concentration of reactants.

i.e. rate (r)∝(C”),

where C=concentration & n=orderofthereaction
or,

r= KC^n ;K=constant.

when concentration increases, number of particles per volume increases too. rate of reaction is all about particle colliding with each other.

so, when concentration increases, frequency of collision increases too because concentrated solution have many particles. so, frequency of effective collision increases. and rate of reaction increases.
