Question

During a reaction with solids generally the _______ the size of each piece, the larger the total surface area. This means _______ collisions and a greater chance of reaction.

A. smaller, more
B. larger, more
C. larger, less
D. smaller, less

Answer 1

Answer: A. smaller, more

Explanation: Founders Educere answer

Answer 2

A

Step-by-step explanation:

I'm assuming this question implies that the surface area is in relation to the volume of the pieces. In that case, the SMALLER the size of each piece, the larger the surface area. This is because more particles are able to fit into the container if they are smaller, leading to more surface area. Since more pieces can fit into the container, MORE collisions happen according to collision theory.
