2-false

3-false

4-true

Explanation:

The reaction rates depend on many factors, one of them is the amount of reagents, the temperature, and the presence or absence of catalyst.

Catalysts accelerate the reaction rate, as does the increase in the amount of reactants.

On the other hand, low temperatures, low amounts of reagents could slow down.
