# How can crushing something into small pieces affect the rate of the reaction?

## How can crushing something into small pieces affect the rate of the reaction?

Reaction depends on collisions. If a reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area on which collisions can occur, the faster the reaction. Usually, an increase in temperature causes an increase in the reaction rate.

Why crushing a solid into a powder increases the rate of reaction?

An increase in surface area results in more frequent collisions due to the greater surface area of the reactant species and the reaction will proceed at a faster speed. Therefore, grinding a solid reactant into powder will increase the reaction rate.

### How does particle size speed up a reaction?

Surface Area / Particle Size Breaking the reactant into smaller pieces increases the surface and more particles are exposed to the reaction mixture. This results in an increased frequency of collisions and therefore a faster rate of reaction.

How can you increase the speed of the reaction?

How to increase reaction speed

1. raise the temperature;
3. increase the concentration of reagents;
4. change the aggregate state of reagents, reduce their size (increase the area of contact of substances).

#### Why do smaller particles react faster?

Decreasing the size of the particles, which make up a given weight, will increase the number of particles represented by the same weight. Smaller particle size results in an increase in the rate of reaction because the surface area of the reactant has been increased.

Why do liquids react faster than solids?

This is because the liquid and the solid can bump into each other only at the liquid-solid interface, which is on the surface of the solid. Therefore, increasing the surface area of the solid will expose more solid molecules to the liquid, which allows for a faster reaction.

## Which factor increases the reaction rate by increasing particle speed?

Temperature
Temperature Effects As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate. Hence the reaction rate of virtually all reactions increases with increasing temperature.

Why does a higher concentration make a reaction faster?

Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

### Why does a small particle size generally cause a reaction faster?

By decreasing the particle size of a reactant, we are increasing its surface area. A smaller particle size of reactants provides a greater surface area that collisions can take place on. The greater the surface area, the faster the rate of reaction.

What are five ways to speed up a reaction?

5 ways to increase reaction speed

1. Heat it up to speed it up: increasing temperature.
2. The opposite of social distancing: increasing concentration or pressure to increase reaction speed.
3. Divide and conquer: decreasing particle size to increase reaction speed.
4. Pro gamer move: dropping a catalyst.

#### What affects the speed of a reaction?

Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

Why does decreasing particle size increases the rate of reaction?

## Why does grinding a solid into a powder increase reaction?

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased: More particles are exposed to the other reactant, there are more collisions, the rate of reaction increases.

Why does breaking reactant into smaller pieces speed up a reaction?

Why would breaking a solid reactant into smaller pieces speed up a reaction? Breaking a solid reactant into smaller pieces would speed up a reaction because the reactants would be more evenly distributed. Leaving the reactant whole would cause a need for a lot of extra stirring to ensure even distribution.

### When do particles collide with the surface of the solid?

when particles collide with the surface of the solid. If the area of the solid surface is made bigger. then more particles can collide with it per second. and the rate of the chemical reaction increases. You can increase the surface area of a solid by breaking. it down into smaller pieces (see also nanoparticles).

How can you increase the surface area of a solid?

You can increase the surface area of a solid by breaking. it down into smaller pieces (see also nanoparticles). A solid that is broken down into a powder has the largest. surface area and therefore has the fastest reaction rate.
