Take is easy,,,,,catalyst increase the rate of chemical reaction and inhibitor decrease it...
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.
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.
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.
Scientists can model the effects of reactant concentration on reaction speed by conducting controlled experiments where they vary the concentration of one or more reactants while keeping other conditions constant. By measuring the rate of reaction—often through changes in concentration, pressure, or volume over time—they can establish a relationship between reactant concentration and reaction speed. This data can be analyzed using rate laws and kinetic models to predict how changes in concentration will influence reaction rates under various conditions. Additionally, computer simulations can be employed to visualize and further explore these relationships quantitatively.
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.
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 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.
Yes, the rate constant can change with concentration in a chemical reaction.
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.
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.
If the reaction speed has not already peaked, then it will increase
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.
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.
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.
Temperature can change the speed of some reactions.
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.

Enzymes are biological catalysts that facilitate chemical reactions, so their availability and activity can significantly influence the speed of reactions within a cell.
