    I think co is best redusing agent below temperature T but coke is better redusing agent after temperature T.

      But we should consider lower temperature only so CO is best

    Mam if we check the number of moles it is decreasing in case of CO to CO2 which means it is negative, so randomness decreases, so entropy also decreases. Acc. To the thermodynamic eqn, change in Gibbs energy is positive even for low or high temp. But if you take in case of C to CO change in Gibbs energy is negative at low and even in high temp. So coke is the best reducing agent. In CO the rule number 2 that u gave for priority is ruled out!!!!!

    Your doubt is that C->CO ....{1}. stands below FeO line than CO->CO2.....{2}. then why the answer is CO.
    But {1} stands below FeO line at higher temperature & {2} stands below FeO line at lower temperature
    Point is to give priority to lower temperature.CO->CO2 is better as :-
    *It is at lower temperature (since low temperature is favourable)
    *It's 🔺G value is negative at lower temperature.
    Hence {2} is better R.A. 🙏

    Mam but in this case the Gibbs free energy is increasing of CO so how can we say that it is the best reducing agent?? Plz explain mam..

    • @rajar1885
      @rajar1885 4 ปีที่แล้ว +12

      yeah, it is increasing among the three but it is still below 0 so, at temperature below t co is the best reducing agent and above temp t c is the best reducing agent . GOT IT!

    • @PalagiriLalitha
      @PalagiriLalitha 4 ปีที่แล้ว +2
