When there is an increase in an object or medium's temperature, its particles have increase kinetic energy. Temperature is the measure of the average amount of kinetic energy within an object or medium.
What else can I help you with?
Does adding a catalyst increase the number of particles of a substance available to react in a chemical reaction?
No, the catalyst doesn't increase the number of reactant particles.
What does not increase the number of particles of a substance available to react in a chemical reaction?
A change in state (solid to liquid) does not increase the number of particles available to react because the same number of particles are still present in the substance.
Why does freezing temperature generally increase the rate of a chemical reaction?
Consider kinetic theory. Since heat is the rapid movement of particles, the more temperature there is, the more movement. If the particcles in a chemical reaction are moving constantly, they are much more likely to collide and react with one another.
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.
Will aluminium react with water?
Aluminum will not react with water at normal temperatures. Increase the temperature greatly, and just about any two things will react, though.
Does increasing the surface area increase or decrease the rate of a chemical reaction?
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
Does increasing concentration increase the rate of reaction?
increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
What do concentration surface area and temperature have in common?
Concentration, surface area, and temperature all affect the rate of chemical reactions. Increasing concentration increases the number of reactant particles colliding, larger surface area allows for more contact between reactants, and higher temperature provides more energy for particles to react.
How does increasing temperature increase the number of reactions?
It increases the collisions that have enough energy to react (apex)
What is the study of how matter and energy react?
Physics is the study of how energy and matter react.
What are the two things a scientist can do to cause some substances that are mixed together to react?
A scientist can increase the temperature of the substances to provide energy that enhances molecular movement, which can lead to more frequent and energetic collisions between reactive particles. Additionally, they can increase the concentration of the reactants, which raises the likelihood of interactions between them, thereby promoting a chemical reaction.
If the temperature of a chemical reaction is increased the reaction rate?
It depends if the reaction is endothermic (requires heat/energy) or is exothermic (requires no heat/energy and produces heat/energy). In general, most reactions are endothermic and require some amount of energy to 'go' and hence, an increase in temperature will increase the rate of reaction. However, in exothermic reactions, introducing heat can halt the reaction as well as reverse it, if said reaction is reversible.
