    Did anybody get the Kc Value to be 0.351?
    Dw a few people here have already confirmed they got this.

    As for me I don't have a clue as to what I got in this yesterday as I just had a 2 hour Eco exam and a 3 hour Accounts exam today

    No effect on Kc. Kc is only affected by changes in temperature not concentration, or pressure.

    i think so , but some of great students state that that is a error in calculating the kc value for studentB , so kc has changed... the i don't understand what they are talking about

    There is no effect but I did in last seconds and something went wrong with my crazzy mind and I wrote that since products decrease kc would decrease but it isn't so actually!

    I don't remember exactly what I wrote but it had to do that Student B missed some steps including recrystallisation, many impurites will still be there and the value of Kc will decrease however I believe it's wrong because Kc is only affected by temperature
