I think it is supposed to be B ... :/

thomaster · Answer

nooo increasing reactant concentration will allways increase the reaction rate. definitely A.

anonymous · Answer

but when u have less reactant it will increase the rate of reaction..

thomaster · Answer

@Ivanka123 that's not true. There are more ways to increase a reaction rate.
-Increasing temperature (molecules move faster)
-Increasing concentration of reactants (more collisions)
-Adding a catalyst (speeding up the reaction)
-Increasing surface area (grind something to powder)
-Stirring (mixing the reactants)
