How is a catalyst different from the reactants and products of a chemical reaction?
A catalyst is not consumed in a chemical reaction, unlike reactants that are consumed to form products. Catalysts lower the activation energy required for a reaction to occur, increasing the reaction rate without being permanently changed or used up in the process. Reactants are the starting materials that undergo a chemical reaction to form products, which are the final substances produced at the end of the reaction.
What are the two important classes of catalysts?
The two important classes of catalysts are homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase from the reactants. Each class has its own advantages and applications depending on the specific reaction and conditions.
The substances used to start a chemical change are called?
The substances used to start a chemical change are called reactants. Reactants are the starting materials that undergo a chemical reaction to produce new substances called products.
What factors influence the position of equilibrium in a chemical reaction?
The position of equilibrium in a chemical reaction is influenced by factors such as temperature, pressure, concentration of reactants and products, and the presence of catalysts. These factors can shift the equilibrium towards the formation of more products or more reactants, depending on the conditions of the reaction.
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 are the examples of heterogeneous and homogeneous?
catalysts which are in the same phase to that of reactants and products
How many types of catalyst are there?
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
How do catalysts affect the energy reactant?
Catalysts lower the activation energy required for a chemical reaction, allowing reactants to convert into products more easily and quickly. They provide an alternative reaction pathway that requires less energy, but they do not alter the overall energy of the reactants or products. By facilitating the reaction, catalysts increase the reaction rate without being consumed in the process.
What are the substances that interact during a chemical reaction?
The substances that are combined in a chemical reaction are called the reactants, and the end substances are called the products.Compounds involved in a process but not found in the end products are called catalysts.
What reacts to produce products?
In a chemical reaction, reactants are the substances that undergo change to form products. The nature of the reactants, their concentrations, temperature, and the presence of catalysts all influence the reaction process. When reactants interact, they break and form bonds, leading to the creation of new chemical substances known as products.
What factors may change the rate of a chemical reaction?
There could be many such as concentration of reactants, temperature, pressure, volume, presence of catalysts etc., depending on the state of matter of the reactants and products.
What compounds carry out a chemical reaction?
In a chemical reaction, the reactants are the compounds that undergo a change to form products. These reactants interact with each other, resulting in the formation of new compounds or substances. The products are the compounds that are produced as a result of the reaction between the reactants.
Reaction rate refers to how quickly or slowly the?
A reaction rate refers to the speed at which reactants are converted into products during a chemical reaction. It is influenced by factors such as temperature, concentration of reactants, and presence of catalysts. Higher reaction rates indicate a faster conversion of reactants into products.

Can atoms that are not in the reactants end up in the products of a chemical reaction?
Yes, atoms that are not present in the reactants can end up in the products of a chemical reaction if they are introduced during the reaction. This can occur through several means, such as the use of catalysts, the presence of solvent molecules, or the incorporation of additional reactants. For example, in combustion reactions, oxygen from the air is added to the reactants, resulting in products that contain atoms not originally present in the starting materials. Thus, the final composition of the products can include atoms from outside the initial reactants.
The substances used to start a chemical change are called?
The substances used to start a chemical change are called reactants. Reactants are the starting materials that undergo a chemical reaction to produce new substances called products.
