Question
_________ substance which accelerate the chemical reaction, however itself doesn’t undergo any chemical change.
- Compound
- Product
- Reactant
- Catalyst
Hint:
The activity of catalysts is Similar to enzymes.
The correct answer is: Catalyst
- A catalyst is a substance that changes the rate of a chemical reaction without causing a chemical change. Catalysis is the process of adding catalysts to facilitate reactions.
- During chemical reactions, bonds between atoms in molecules are broken, rearranged, reassembled, and atoms recombine into new molecules.
- Catalysts make this process more efficient by lowering the activation energy, the energy barrier that must be overcome for chemical reactions to occur.
