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 is the rate of disappearance equation used to determine the speed at which a substance is consumed or transformed in a chemical reaction?
The rate of disappearance equation is used to calculate how quickly a substance is used up or changed in a chemical reaction. It helps determine the speed at which the reaction is happening.
How is the rate of reaction compared with the time the reaction is carried out?
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
Rate of reactions?
The rate of a reaction is the time it takes for a reaction to take place. The rate of reactions can be affect by different factors such as the temperature, the air pressure, the concentration of each substance and whether a catalyst is used (a catalyst is something that lowers something's activation energy so the reactants have more energy to react). A reaction happens when atoms collide with each with a big enough force therefore a bigger surface area would help speed this up. Also the amount of energy the particle/atoms have helps. With these factors you can determine the speed at which a reation happens. Any questions?
Are catalysts included in rate laws and how do they affect the overall reaction rate?
Catalysts are not included in rate laws because they do not affect the overall reaction rate. Instead, catalysts speed up the reaction by providing an alternative pathway with lower activation energy, allowing the reaction to occur faster without being consumed in the process.
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?

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.
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 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.
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.
Substance that speeds up the rate of chemical reaction?
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
