The correct Answer is:
To solve the question regarding the two statements about catalysts and their effectiveness in finely divided form, we can break down the reasoning step by step. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - **Statement 1**: "A catalyst is more effective in finely divided form." - This statement is based on the principle that catalysts work by providing a surface for reactants to adsorb onto. The more finely divided the catalyst, the greater the surface area available for reactions to occur. 2. **Understanding Statement 2**: - **Statement 2**: "Finely divided form has more surface area." - This statement is true because when a substance is divided into smaller particles, the total surface area increases. For example, if you take a solid and grind it into a powder, the surface area exposed to the surrounding environment increases significantly. 3. **Analyzing the Relationship**: - Since Statement 1 asserts that a finely divided catalyst is more effective and Statement 2 explains why (due to increased surface area), we can conclude that both statements are true. - The effectiveness of a catalyst is directly related to the amount of surface area available for the reactants to interact with the catalyst. 4. **Conclusion**: - Both statements are correct, and Statement 2 provides a valid explanation for Statement 1. Therefore, the correct answer is that both statements are true, and Statement 2 is the correct explanation of Statement 1. ### Final Answer: Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation of Statement 1. ---
