Reaction rate

Postby 204568380 » Wed Feb 10, 2016 7:48 pm

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

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?

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