according to the answer key for my midterm , yes :D but i'm wondering the reason too.
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
The four steps of the reaction process typically include: 1) Reactant Preparation - where reactants are gathered and prepared for the reaction; 2) Collision - where reactant particles collide with sufficient energy and proper orientation; 3) Transition State Formation - where the reactants reach an activated complex or transition state; 4) Product Formation - where the products are formed as bonds are broken and new bonds are created, resulting in a release of energy or change in state.
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.
A catalyst cannot change the equilibrium position. However, it can change its rate.
Catalyst is not a reactant.

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.

A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.

why is technology called a catalyst foor change?
They change the orientation.
A catalyst cannot change the equilibrium position. However, it can change its rate.
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.
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.
