Homework Help: Chemistry equilibrium

  1. Apr 13, 2007 #1
    consider the reaction
    2SO2 + O2 <---> 2SO3

    A SHIFTS TO THE LEFT
    B SHIFTS TO THE RIGHT
    C NO CHANGE

    ADDITIONAL SO2 IS INJECTED INTO REACTION VESSEL
    I PICKED B

    SOME SO3 IS REMOVED FROM THE REATION VESSEL
    I PICKED B AGAIN

    THE SIZE OF THE REACTION VESSEL IS DECREASED
    NOT SURE B OR C

    SOME He IS INJECTED INTO REATION VESSEL
    NOT SURE B OR C

    The questions you have concern the 3rd and 4th question. Explain why you pick b or c for these questions.

    Putting more material in the same volume or the same amount of material in a smaller volume changes the concentration of the material... and you know how changing the concentration affects equilibrium.
