Why does the rate of a reaction increase when the concentration of reactants is increased?

Chemistry

leva [86]3 years ago
5 0

If reactants eventually collide, there is an occurrence of reaction.

<span> 
Therefore, when there is an increase concentration of reactant, meaning to say that there are several moles of it every unit volume. An example of this is a room having hundred of people will absolutely get higher concentration compared to a room with one individual only. 

Pertaining to effective collisions, if ever there is an increase of concentration, the frequency and rate of effective collisions among reactants surges in such a way that the rate of reaction also surges. Same with passing into a room with only 1 individual compared to hundred people blind persons, you probably want to proceed to the room with several people.</span>

<span>This is the simple logic behind that scientific existence.</span>

IrinaK [193]

Answer:

The answer is

<h2>40.0 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass = 420 g

density = 10.5 g/cm³

The volume is

volume =  \frac{420}{10.5}  \\

We have the final answer as

<h3>40.0 mL</h3>
