Increasing a reactants surface area would:

• Increase the rate the reaction happens

• Decrease the rate a reaction happens

• Have no effect on the reaction rate

Organize these options into the right categories (2 each)

Groups:

(a) Increases the Rate of a Reaction

,

(b) Decreased the Rate of a Reaction

• Lower Surface Area

• use of a catalyst

• Higher concentration of reactants

• Lower Temperature
