Homework Help: Science

Posted by Deqa on Tuesday, March 20, 2007 at 12:36am.

Hello :)

my name is Deqa,

i was wondering if anyone knew the affects of a state of a substance on the reaction

so generally speaking does it matter if a solid is dissolved in a solution
or is it faster for a solution be added to another solution

basically im wondering if the state of a substance matters to the reactions?

A reaction will proceed faster if the reactants are dissolved in a solution, than if one or both reactants were undissolved solids. That is because all of the molecules are free to collide with molecules of the other reactant.

Diluting the reactants will slow down the reaction rate, however.
