Question

surface area of reactants is part of the nature of reactants. would you expect increasing the surface area of reactants to increase or decrease the reaction rate?

increase! the greater the surface area, the greater the energy of collisions.

increase! the greater the surface area, the greater the chance for collisions.

decrease! the greater the surface area, the smaller the chance of collisions.

decrease! the greater the surface area, the lesser the energy of collisions.

Explanation:

In chemical reactions, a larger surface area of reactants exposes more particles to potential collisions. Collisions between reactant particles are necessary for a reaction to occur. So, a greater surface - area leads to a higher probability of collisions, thus increasing the reaction rate.

Answer:

B. Increase! The greater the surface area, the greater the chance for collisions.
