catalyst-by lowering activation energy
A catalyst is a substance that speeds up the rate of a chemical reaction.
A catalyst is something that brings about a result or change by speeding up a chemical reaction or initiating a process. It is a substance that increases the rate of a reaction without being consumed in the process.
A substance with a definite chemical makeup is called a chemical compound. This means that it is made up of specific types and numbers of atoms that are chemically bonded together in a fixed ratio. Examples include water (H2O), salt (NaCl), and glucose (C6H12O6).
Four types of energy that might make up the internal energy of a substance are kinetic energy (due to movement of particles), potential energy (due to positions of particles in a field), chemical energy (due to chemical bonds), and thermal energy (due to temperature of the substance).
Increasing the heat energy of a substance causes the particles to move faster and have more kinetic energy. This can lead to an increase in the substance's temperature, change in state (solid to liquid to gas), or possibly result in chemical reactions depending on the substance.
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
A substance that speeds up a chemical reaction is known as a CATALYST.

A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy needed for the reaction to occur, without being consumed or permanently altered in the process.
