How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
Does adding heat energy affect the rate of reaction in a chemical change?
it depends on what chemicals used
What can change the rate of reaction of enzymes?
Heat can change the rate of reaction
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 concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
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
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
What are two factors besides particle size that might affect the rate of the reaction?
A particles kinetic energy (movement) caused by heat energy as heat energy could be transformed.
When would pressure affect the reaction rate?
if gases are involved in the reaction.
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
Does concentration have an affect on reaction rate?
Yes.why
Where surface area is not affect the rate of a reaction?
Surface area affect the reaction rate because the contact between finely divided particles is improved.
