Homework Help: Need more help

  1. Feb 26, 2008 #1
    A reaction of the form aA = products is second order with a rate constant of 0.169
    L/(mol s). If the initial concentration of A is 0.159 mol/L, how many seconds would it
    take for the concentration of A to decrease to 6.07 x 10^-3 mol/L ?

    how to solve these

    If your not going to help, dont bother to post any rude comments. That is not how you help someone learn.

    NO that is what the HOMEWORK forum is for. And no one is going to help you there either because you haven't even shown that you have tried any work on your own.

    Ok jackass. Next time, just refer them to the Forum rules.

    FAQ: Why hasn't anybody answered my question? - https://www.physicsforums.com/showthread.php?t=94384

    Anyways Kitty ...

    1) What is the equation you will need for a 2nd order reaction?
    2) What values do you have? Initial/Final concentration ... etc?

    Refer to the image for equations:
