Reaction rate

[204568380]

Why does the reaction rate depend only on [R] (the concentration of the reactant)?

[Pauline Tran 2G]

Reaction rates will generally decrease with time as the reactant concentration decreases. The reactant is what fuels the reaction; once there is no more reactant left, the reaction generally stops.

If looking at the reversed reaction, does the rate depend on the reactants that were the products, or does it still depend on the original reactants?

[Arsheeta Kumar 1B]

The rate would depend on the products, because in a reverse reaction, you're now putting the reactants in the products position.
