Question 10
Which situation would react faster and why?
a
Example B 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 high surface area.
d
Example A would be faster because of a low surface area.
c
Example B would be faster because of a high surface area.
The correct answer is c. Example B would be faster because of a high surface area. A reaction occurs when particles collide. A higher surface area means more exposed surfaces for particles to collide with, increasing the chances of reaction. Therefore, Example B with a high surface area would react faster compared to Example A with a low surface area.
To determine which situation would react faster, we need to compare the surface area of examples A and B. The larger the surface area, the faster the reaction will occur.
Option a suggests that Example B would be faster because of a low surface area. However, this is incorrect because a low surface area would mean less exposure to reactants, resulting in a slower reaction.
Option b suggests that Example A would be faster because of a high surface area. This is the correct answer. When the surface area is increased, more reactant particles are in contact with each other, leading to a faster reaction.
Option c suggests that Example B would be faster because of a high surface area. This is incorrect as it contradicts the principle stated above.
Option d suggests that Example A would be faster because of a low surface area. This is also incorrect for the same reason as option a.
Therefore, the correct answer is option b: Example A would react faster because of a high surface area.
