Why does a higher concentration increase the rate of reaction?

Chemistry
1 answer:
Sauron [17]3 years ago
5 0

Answer:

A higher concentration will increase rate of reaction because in a conc substance the particles are more clustered together and this causes more effective collisions thus increasing the rate of reaction.

Does the H₂SO4 solution contain ions?<br> O yes<br> O no
Artist 52 [7]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the concept of Ions .

If we see the reaction.

H2SO4 ==> 2H+ + (SO4)2-

Here you can see, H+ ( Hydrogen ions) and (SO4) 2- ( sulphate ions) are the ions when the H2SO4 is dissolved in water.

What is meant by saying that the latent heat of vaporization of water is 22. 5×10^5 j/kg.
andrey2020 [161]

It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.

Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.

Boiling point of the water is 100°C.

Joule (J) is the standard unit for energy (in this example heat).

Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

When determining reaction orders by experiment, the most common procedure is to ______. Multiple choice question. keep all react
Scilla [17]

Answer:

change the concentration of one reactant while keeping the other concentrations constant

Explanation:

For a given reaction;

A +  B --> C + D

The reaction rate may be given as;

Rate = k[A][B]

In the above rate equation, the orders of both reactants ( A and B) is 1 . Reaction order is basically how the concentration of the reactant affect the rate of the equation.

The correct option is;

change the concentration of one reactant while keeping the other concentrations constant.

That way, one can monitor how a particular reactant affect the rate of the reaction.
