Reaction kinetics question

  1. Sep 24, 2005 #1
    I'm really having trouble with this question, can someone help me with an explanation?

    Is it possible to vary the factors of concentration, surface area, and temperature in a way that would prevent a reaction from happening? explain your answers in terms of collisions.

    Will catalysts always speed up reactions?

    thanks in advance

    First have you read your textbook? What ARE "concentration" and "surface area" and what do they have to do with reactions? What is the definition of "catalyst"?
