. For the gas reaction at low pressure

2NOBr ¡ê 2NO + Br2 ¥ÄH = +61.1 kJ

which of the following statements are true?

a) Adding more Br2 shifts reaction to the right

b) Removing some NOBr shifts reaction to the left

c) Increasing temperature shifts reaction to the right

d) Changing temperature is the only thing that does not affect Kp

e) The use of a catalyst will not cause any change in the concentrations once equilibrium is reached

  • Chemistry -

    oops the reaction should be
    2NOBr <-> 2NO + Br2 (delta)H = +61.1 kJ

  • Chemistry -

    It's tough to read the equation. I can't make out the symbols. Where is the arrow? What are your thoughts on the question?

  • Chemistry -

    Adding Br2 will shift the reaction to the left.
    Removing NOBr will shift the reaction to the left.
    You try the others.

  • Chemistry -

    I just fixed the equation above but here it is again 2NOBr <-> 2NO + Br2 (delta)H = +61.1 kJ
    I thought b and e are true however the computer keeps saying that answer is wrong.

  • Chemistry -

    b and e ARE true. You can take that to the bank. The computer is (a) wrong or (b) or you keying into the wrong question. a,c,d or not true.

  • Chemistry -

    no I've entered b and e several times before into the computer (and now again) for the correct question so now I am going to email my instructor, thank you

  • Chemistry -

    If your instructor thinks b and e are NOT true I would like to know it AND I would like to know the reason why. LeChatelier may turn over in his grave.

  • Chemistry -

    Haha yes he probably will. I will let you know.

  • Chemistry -

    My profesor says that b and e are true but c is also true. The reaction will shift toward the right with a temperature increase because it is endothermic. I did type in bce before but because the computer said it was incorrect I changed my answer. :( It is too late to fix it now, however thank you for your help.
