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 role do catalysts play in chemical reactions?
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
What type of reaction is dependent the most upon the concentration of the products or reactants?
The rate of a chemical reaction that is most dependent on the concentration of the reactants is known as a first-order reaction. In a first-order reaction, the rate of the reaction is directly proportional to the concentration of one reactant. Therefore, changes in the concentration of the reactant directly impact the rate at which the reaction proceeds.
In what kind of reaction can the products form the reactants?
In a reversible reaction, the products can convert back into the reactants given appropriate conditions. This is often seen in chemical equilibrium where the forward and reverse reactions occur at the same rate.
What kind of chemical reaction needs a constant supply of energy?
If a reaction requires a constant input of energy, the products are higher in energy than the reactants. This type of reaction is known as endothermic, since it involves an increase in energy of the system. Conversely, reactions that release energy are known as exothermic.
During a chemical reaction what remains constant?
In a chemical reaction, the total mass of the reactants and products remains constant, according to the Law of Conservation of Mass. This means that atoms are rearranged but not created or destroyed during a chemical reaction.
What jobs do enzymes do in the body?
type of protein that speeds up the rate of a chemical reaction in your body.
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.
Is salt a chemical reaction?
A salt is a type of chemical compound, not a reaction.
Is decomposition a type of reaction?
Yes, decomposition is a type of chemical reaction. This chemical reaction breaks down a compound into its individual elements.
