What else can I help you with?
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Can a catalyst change the rate constant for a reaction?
A catalyst can change the rate constant for a reaction by providing an alternative reaction pathway with lower activation energy. This lowers the energy barrier for the reaction, allowing more reactant molecules to successfully undergo the reaction, thus increasing the rate constant for the reaction.
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
Which does a catalyst not change?
Catalyst is not a reactant.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What are the ways rates of chemical change can be changed?
Rate of chemical change can be altered by 1. Changing the temperature. 2. Changing the pressure (if gases are involved). 3. Changing the particle size of a solid reactant. 4. Changing the concentration of a dissolved reactant. 5. Adding a suitable catalyst.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
Can a catalyst change the rate constant for a reaction?
A catalyst can change the rate constant for a reaction by providing an alternative reaction pathway with lower activation energy. This lowers the energy barrier for the reaction, allowing more reactant molecules to successfully undergo the reaction, thus increasing the rate constant for the reaction.
Why is technology called a catalyst for change?
why is technology called a catalyst foor change?
Do rotations preserve or change the orientation of the figure?
They change the orientation.
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
What is the difference between a reactant and a catalyst?

This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
Does temperature act as a catalyst?
No, temperature is not a catalyst. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while temperature is a measure of the average kinetic energy of particles in a system. Temperature can affect the rate of a reaction by influencing the frequency of collisions between reactant molecules.
