Particles move at a faster rate at higher temperatures, than they do at lower temperatures. This is do to the fact that heat is a form of energy. When a particle has more energy is moves faster.

∙ 9y agoThe rate of nearly every chemical reaction will increase with high temperatures. In order for reactant to even occur, particles must contain a certain amount of activation energy.

Why cycle tubes filled with air burst in summer?
The tires are filled with air particles, whose behaviour is governed by what is known as the kinetic molecular theory. In simple terms, during the summer where temperatures are (assumingly) higher, the air particles have more energy (high temp. = higher average kinetic energy). With higher energy, they are moving about inside the tire with higher speed and collisions are more forceful (and common). Thus, these particles tend to occupy more space, and so the tire is forced to expand, eventually bursting.
A physical property that tells you how hot or cold matter is?
The physical property that tells you how hot or cold matter is, we call temperature. Temperature consists of random motion on the atomic or molecular scale. Faster moving particles have higher temperatures.
Decreasing the temperature of a reaction decreases?
According to collision theory, decreasing the concentration of the reactants in a chemical reaction decreases the frequency of the collisions between reactants, and therefore decreases the rate of the reaction.
Is it true that a low concentration of a chemical slows reaction rate?
I would point your studies towards collision theory. It's not that a low concentration necessarily slows down a reaction, but that a low concentration will have a slower reaction rate than a higher concentration of reactants. A lower concentration means a lower number of reactants in solution, meaning it is less likely for the reactants to collide and create products. With a lot of reactants, it is much more likely for collisions to occur.
In general what true about places at higher altitudes?
They have cooler temperatures than places at lower altitudes.
Do particles in matter move more quickly at lower temperatures or higher temperatures?
At higher temperatures.
What is the effect of varying the concentrations of each of the reactants?
reaction rate depends upon three things: temperature (higher temperature means faster reactions), particle size (smaller particles leading to an increase in surface area means faster reactions) and concentration of reactants (the higher the concentration, the higher the chance for particle collisions). Rate of reaction is based upon particle collisions. Higher temperatures yield more and stronger collisions, hence there is higher rate of reaction. Smaller particles (giving more surface area) means more collisions (reactants are not "stuck" on the inside of clumps of substances, waiting to collide when the outer particles get out of the way). Higher concentrations let more particles find each other to react; time is not wasted by substances floating around not having a chance to collide with other substances.
What happens to particles in a substance whe the sustance's temperature increase?
At higher temperatures, the particles move around faster.
At higher temperatures what do particels do?
As the temperature of a substance increases, its particles move faster.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
How does the particles of matter react to temperature?
It is widely accepted within the scientific field that higher levels of heat to cause particles to move more quickly. An air molecule, for example, will be moving much faster at higher temperatures than it would at lower temperatures.
How are the concentration of the reactants and reaction rate related?
rate laws a+the higher the concentration = more particles = higher chance of a collision happening = higher/faster reaction rate
What is the connection between the energy of the water particles at higher temperatures and the resulting solubility of sucrose?
the higher the temperature, the more contact there is to the object to make the solvent mix with the salute to make the sucrose.
Why are hot gas particles moving faster than cool gas particles?
High temperatures weaken the magnetic fields that keep atoms bound together. The weaker the field, the more freely the atoms move around. Therefore, free particles and atoms at higher temperatures move faster than bound ones.
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
How do particles move at higher temperatures compared to how they move at lower temperatures?
particles move faster, such as when you are hot and you want to get away from everyone. lower tempertures move slowly and gather up into groups, as if u were cold and you would want a group hug to get warmer, also you move slower because it is cold.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
