Q: What is the main characteristic of a catalyst in surface reactions?
Solution:
A catalyst lowers the activation energy of a reaction without being consumed in the process.
Steps: 4
Show Steps
Step 1: Understand what a catalyst is. A catalyst is a substance that speeds up a chemical reaction.
Step 2: Learn about activation energy. Activation energy is the energy needed to start a reaction.
Step 3: Know that a catalyst lowers the activation energy. This means the reaction can happen more easily and quickly.
Step 4: Remember that a catalyst is not used up in the reaction. After the reaction, it can still be used again.
