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.

Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
How does the rate law show how concentration changes change the rate of reaction?
as concentration increase the faster the rate of reaction and vice versa
What happens to the reaction rate as the reactants get used up in a reaction?
The rate of a reaction begins to decreases as reactant are used up
What is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
What can change the rate of reaction of enzymes?
Heat can change the rate of reaction
Does adding heat energy affect the rate of reaction in a chemical change?
it depends on what chemicals used
What are two major factors that change the rate of a reaction?
heat (energy)/ concentration/ surface area
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
Does temperature act as a catalyst?
yes.. No. That's no. Heat controls the rate of reaction, but a catalyst is defined as a *chemical agent* (element/ compound) that alters the rate of reaction.
What do enzymes change about a chemical reaction?
The Reaction Rate
Can you change the rate of chemical change?
Heat increases the rate of reaction as heat makes particles vibrate and increases the frequency of collisions between particles. This means that more particles can react in a shorter amount of time.A catalyst also increases the rate of reaction as it provides extra surface area for the reactions to happen on and in some cases, attacks certain bonds to initiate the reaction.If you wanted to decrease the rate of reaction, cooling the vessel would do the trick.
What is the rate of the reaction?
The rate in which a certain reaction takes place in. The rate of reaction can be changed by:Using catalystsIncreasing the surface areaUsing a larger quantityApllying more heat
Will introducing a competitive inhibitor change the rate of reaction?
It slowed the reaction rate down
What happens if the beta-galactosidase in not available?
the rate of reaction will change
