What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What do enzymes change about a chemical reaction?
The Reaction Rate
Is The rate of a reaction is the change in concentration per unit?
Yes, the rate of a reaction is defined as the change in concentration of a reactant or product per unit time. It measures how quickly a reaction occurs, typically expressed in terms of molarity per second (M/s). This rate can vary depending on factors such as temperature, concentration, and the presence of catalysts.
Can you change the rate of chemical change?
Heat increases the rate of reaction as heat makes particles vibrate and increases the frequency of collisions between particles. This means that more particles can react in a shorter amount of time.A catalyst also increases the rate of reaction as it provides extra surface area for the reactions to happen on and in some cases, attacks certain bonds to initiate the reaction.If you wanted to decrease the rate of reaction, cooling the vessel would do the trick.
What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.

What can change the rate of reaction of enzymes?
Heat can change the rate of reaction
How is the reaction rate measured in chemical reactions?
The reaction rate in chemical reactions is measured by monitoring the change in concentration of reactants or products over time. This can be done by measuring factors such as the amount of gas produced, color change, or temperature change. The rate of reaction is typically expressed as the change in concentration per unit time.
If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
If the order of a reactant is zero, its concentration will not affect the rate of the reaction. This means that changes in the concentration of the reactant will not change the rate at which the reaction proceeds. The rate of the reaction will only be influenced by the factors affecting the overall rate law of the reaction.
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
What do enzymes change about a chemical reaction?
The Reaction Rate
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.
Is The rate of a reaction is the change in concentration per unit?
Yes, the rate of a reaction is defined as the change in concentration of a reactant or product per unit time. It measures how quickly a reaction occurs, typically expressed in terms of molarity per second (M/s). This rate can vary depending on factors such as temperature, concentration, and the presence of catalysts.
What factors influence the rate of a forward reaction in a chemical reaction?
The rate of a forward reaction in a chemical reaction is influenced by factors such as temperature, concentration of reactants, surface area, and the presence of catalysts. These factors can affect how quickly the reactants are converted into products.
What does the rate of reaction dependent on?
rate of reaction depends on the amount of reactants
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.
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.
