1 surface area 2 concentration of reactant 3 presence of a catalyst 4 temperature
not sure about the last two...
One other one is:
pressure of gaseous reactants or products
Not sure though??
What else can I help you with?
Why does the rate of a reaction speed up?
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
What does catalysis do?
Speed up the rate of a chemical reaction
Is it proteins and catalysts that speed up the rate of a reaction?
Catalysts
How is the term catalyst related to reaction rate?
The catalyst is a substance added to the reaction to speed it up. All in all, thecatalystlowers the reaction rate.
How do enzymes altar the rate of chemical reaction?
speed up the rate odf reacvtion
Is catalyst a product of chemical reaction?
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
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.
Enzymes increase the rate of a reaction by doing what?
An enzyme is a catalyst that speeds up a chemical reaction. It functions by lowering the activation energy required for a reaction to occur, and by reducing the activation energy, the reaction speeds up.
What will not speed up the rate of reaction between a strip of magnesium and hydrochloric acid?
Factors that will not speed up the rate of reaction between a strip of magnesium and hydrochloric acid include decreasing the concentration of the acid, using a larger piece of magnesium, or lowering the temperature of the reaction. These changes either reduce the frequency of collisions between reactant particles or limit the availability of reactive surface area, thus slowing down the reaction instead of speeding it up.
How does a catalyst speed up a reaction at low tempertures?
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.
What changes can be made to a chemical reaction to increase the rate constant"?
To increase the rate constant of a chemical reaction, you can change factors such as temperature, concentration of reactants, presence of a catalyst, and surface area of reactants. These changes can speed up the reaction by providing more energy and effective collisions between molecules.
What three factors can speed up the rate of something dissolving?
Three factors that speed up the rate of dissolution are increased temperature, increased surface area, and stirring the mixture.
