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 Temperature

• use of a catalyst

• Lower Surface Area

• Higher concentration of reactants

An exothermic process is when

• Heat exits a system to the surroundings

• Heat enters a system from the surroundings

• Heat has nothing to do with a system

• Heat breaks up with the system and they're ex's now
