Verified step by step guidance1
Understand the role of a catalyst in a chemical reaction: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
Recognize that a catalyst works by providing an alternative reaction pathway with a lower activation energy, which makes it easier for the reaction to occur.
Differentiate between the terms: Reactant, Product, Catalyst, and Inhibitor. A reactant is a starting material in a chemical reaction, a product is a substance formed as a result of a chemical reaction, and an inhibitor is a substance that decreases the rate of a chemical reaction.
Identify the correct term that matches the description of speeding up chemical reactions and lowering activation energy, which is 'Catalyst'.
Remember that catalysts do not alter the equilibrium of a reaction; they only help the system reach equilibrium faster.
