Question

Which is usually associated with a higher reaction rate?

A.) diluting a solution of the reactants
B.) adding modeling clay to the reactants
C.) removing heat energy from the reactants
D.) using a solid with a high surface area in the reactants

Answer 1

Reaction rate increases when temperature increases, when concentration increases, and when solid reactants have more surface area available (e.g., when the reactants are in smaller pieces). Catalysts are chemicals that raise reaction rates without being consumed in the reaction.

Step-by-step explanation:

Answer 2

D.) using a solid with a high surface area in the reactants

Step-by-step explanation:

Using a solid with a high surface area in the reactants is usually associated with a higher reaction rate.
