What is the chemical reaction that uses heat to decompose an compound?
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
What causes particles to settle the most?
Greater density causes particles to settle faster.
What causes the reaction in chromatography?
physical change causes the reaction in chromatography!
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
What is a process where two nuclei or particles interact to form different particles?
Nuclear Reaction
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.
How do particles heat up?
Whenever direct heat is given to any kind of particles/materials, an exothermic reaction occurs. When an exothermic reaction occurs, heat is released. This is what causes the particles to heat up.

What causes particles to slow down and contract?
what causes particles to slow down and contract

What causes an increased rate of reaction?
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
What are the factors affecting rate of reactoin?
There are 4 factors affecting rate: - Surface area -Temperature - Catalysts -Concentration If the surface area is increased the reaction rate will increase due to more particles being exposed to the reacting chemical, the more particles colliding the quicker the reaction will happen. Temperature causes particles to speed up or slow down, for example in a gas particles are moving very quickly, and therefore they collide more often, this would mean that a reaction would happen quickly since reaction depends on the amount of collisions as well as the strength of collisions. Catalysts are added substances into reactions which only help to speed up the reaction, they are not changed in the reaction and remain the same after the reaction has occurred. If concentration is increased more particles are given the chance to collide, so once again, with more collisions the more quickly a reaction occurs.
Is a change in the number of particles in a suspension a chemical reaction?
This is not a chemical reaction.
Why do faster moving particles or hot particles increase the rate of a reaction?
it move
The subatonic particles released during a nuclear chain reaction are what?
subatonic particles
How does heat change reaction rate?
Collisions need to be formed for a reaction to occur. Therefore, heat boosts the reaction rate because heat causes vibrations to occur, meaning the particles are moving at a greater speed, so therefore creating more collisions and consequently resulting in a boost in the reaction rate.
