Question

Which situation would react faster and why?
a
Example A would be faster because of a low surface area.
b
Example A would be faster because of a high surface area.
c
Example B would be faster because of a low surface area.
d
Example B would be faster because of a high surface area.

Answer 1

To determine which situation would react faster based on surface area, we need to consider that reactions typically occur at the surface of solid particles. A higher surface area allows more area for collisions between reactant molecules, facilitating a faster reaction.

- If **Example A** has a high surface area, it would react faster compared to a similar example with a low surface area.
- Conversely, if **Example B** has a high surface area, it would also react faster than if it had a low surface area.

Based on these principles, if one example (A or B) has a higher surface area compared to the other, then the option suggesting that example with a high surface area would react faster is correct.

Without the specific details on Example A and Example B, I cannot definitively choose one of the options. However, if we are to infer from the options given, the selection would be:

- **b**: Example A would be faster because of a high surface area.
- **d**: Example B would be faster because of a high surface area.

But typically, the answer would be **d** if Example B has the higher surface area, and **b** if Example A has the higher surface area. You would need to provide the specific details about A and B to make a definite conclusion.
