Question

Which would increase the reaction rate?

A) decreasing the reaction temperature
B) decreasing the reactant's particle size
C) decreasing a reactant's concentration
D) increasing a reactant's particle size

Answer 1

B) decreasing the reactant's particle size .

If a smaller reactant size was involved the reaction would occur faster as the quantity to partake in the reaction is smaller, and it would take lesser time compared to a bigger reactant.

Answer 2

B) decreasing the reactants particle size
