∙ 14y agoThe smaller the particles, the faster the rate of reaction, as the surface area is increased, so there is more chance for particles to react. For example, imagine adding 10 grams of powdered substance to a solution; and then add a 10 gram lump of the same reactant. The powdered substance should react fully before the single mass of reactant.

∙ 9y agoBreaking 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.

∙ 10y agoIf you change the size of a reacting solid in an expirement or a process, it will directly affect the speed of the reaction. Therefore, it can either act as a catalyst to increase the speed or to reduce if you take it out.

∙ 7y agoIf a solid is one of the reactants, breaking it into smaller grains should increase the rate of the reaction. This is because the surface area is increased, meaning more particles can come into contact with the other reactant(s).

∙ 15y agoThis is because the smaller the particles are, the more surface area is exposed to the other reactant, therefore increasing reaction rate

Decreasing particle size collision frequency of reactants?
increases
Can you change the rate of a chemical reaction by changing the particle size?
In hetrogeneous reactions (where the reactants are in different states) the size of the particles of a solid may change reaction rate, since the surface is where the reaction takes place, and the surface area is increased when the particles are more finely divided. In general, the smaller the particles the faster the reaction
What is the formula of mean particle size?
Mean particle size=0.94*Lambda/(FWHM*cos(theta)
What is the relationship between porosity bulk density and particle density?
If you were to graph particle size and porosity, it would be a constant slope (horizontal line).Porosity is not affected by particle size.
What is the particle size of gneiss?
1cm
Decreasing particle size collision frequency of reactants?
increases
You can slow down the rate of reaction by?
Decreasing particle size
What reaction means that's the particle size is smaller thus causing more opportunities for collisions hence the reaction rate increases?
The contact between reactants is improved if the particle size is smaller..
Can you change the rate of a chemical reation by changing the particle size of the reaction?
Yes. when the particle size of the reactants are smaller, the surface area is higher. Thus the probability of the occurrence of collisions in the correct orientation is higher. Hence the rate of the reaction is higher.

What happens to the speed of a particle as temperature decreases?
The speed of a particle decreases with decreasing temperature. Decreasing temperature is associated with lower energy states, and the particle will have a lower energy state. It will be moving with less kinetic energy.
What is the difference between particle size and crystallite size?
crystallite is the average size of the particle whereas the particle size denotes the individual size of the particle.
By decreasing this you can speed up a chemical reaction?
Decrease the activation energy to speed up a chemical reaction.
What type of nuclear decay results in the atomic number decreasing by two and the mass decreasing by two?
Emission of an alpha particle.
Decreasing the concentration of the reactants decreases the between particles thereby decreasing the probability that two particles will collide with and with?
rate of collisions, the right orientation, enough energy
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Do particles have fixed size?
Particle size depends on the type of particle.
