  1. Raising the temperature of reactants will speed up a chemical reaction as it make the achievement of the Activation Energy easier. The temperature of individual atoms/molecules in a gas or liquid follow a normal distribution. Raising the temperature forces more atoms/molecules into the 'reaction worthy' side of the distribution.
  2. Sneeky energy pumping. Provide some kind of energy that doesn't raise the temperature but does break-down reactant into more reactive radicals. (light, electric discharge) See the photo-electric effect
  3. Introduce enzymes. Chemicals that aren't consumed in the chemical reaction but provide a lower energy way for the reaction to proceed.
  4. Poisons react opposite to enzymes by inhibiting a lower energy alternative and forcing a higher energy path for the reaction.

Take is easy,,,,,catalyst increase the rate of chemical reaction and inhibitor decrease it...

Is the speed of the reaction influenced by the amount of enzyme in the environment?

Yes. Say each enzyme molecule can do one reaction at a time. You will have more product with 100 enzymes than with 10 in the same amount of time. The rate (speed) of the reaction is the change in concentration of the product divided by the change in time.


How does the concentration of a pure liquid change throughout the course of a reaction?

The concentration of a pure liquid does not change throughout the course of a reaction since it is not involved in the reaction itself. The concentration of a pure liquid remains constant because its molecules do not participate in the reaction.


What affects the speed of reaction in a cell?

The speed of reaction in a cell can be affected by factors such as enzyme concentration, substrate concentration, temperature, and pH levels. Enzymes are biological catalysts that facilitate chemical reactions, so their availability and activity can significantly influence the speed of reactions within a cell. Additionally, the concentration of substrates and the environmental conditions can also impact reaction rates.


What is a change in concentration of a reactant or product over time?

The change in concentration of a reactant or product over time is known as the reaction rate. It is a measure of how quickly reactants are consumed or products are formed during a chemical reaction. This rate is typically expressed as the change in concentration per unit time.


What is the relationship between concentration and reaction rate?

In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.

What effect does the concentration of reactants have on the rate of speed?

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.


The speed at which a reactant will change to a product is proportional to its?

The speed at which a reactant will change to a product is proportional to its concentration. This relationship is described by the rate law of the reaction. Changes in other factors, such as temperature and the presence of catalysts, can also affect the reaction rate.


Does the rate constant change with concentration in a chemical reaction?

Yes, the rate constant can change with concentration in a chemical reaction.


What is concentration per unit time?

Concentration per unit time, also known as rate of change of concentration, is a measure of how quickly the concentration of a substance is changing with respect to time. It indicates the speed at which a substance is being produced or consumed in a reaction or process. This can be calculated by dividing the change in concentration by the time interval over which the change occurred.


What is the effect of increasing the concentration of enzymes in a reaction?

If the reaction speed has not already peaked, then it will increase

What is the average rate of disappearance for the substance in this chemical reaction?

The average rate of disappearance for a substance in a chemical reaction is the speed at which the substance is used up over time. It is calculated by dividing the change in concentration of the substance by the change in time.

How do you calculate the initial rate of a reaction?

The initial rate of a reaction is calculated by measuring the change in concentration of reactants over time at the beginning of the reaction. This is done by dividing the change in concentration by the change in time. The initial rate is typically expressed in units of concentration per unit time.


How can you change the speed of a reaction?

Temperature can change the speed of some reactions.


How do you calculate the initial rate of reaction in a chemical reaction?

To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.
