Bumping the post --- as Ididn't get the answer. Also I edited and made my question simpler.Thanks!


State what equation is being plotted in Ellingham diagram andexplain why the slope is positive.

Is the answer simply,

ΔG =ΔH - TΔS   ?

But, then as the temperature increase,ΔG must become more negative. (as it becomes ΔH <-TΔS. But when you look at the diagram, as temperatureincreases, ΔG becomes close to positive. Would anyone advisewhy?

As for upward slope, I simply thought it's becausethe temperature rise but other explanation says it's to do withΔS as condensed phase reacts with gas to produce morecondensed phase which means the decrease of ΔS.. which Iunderstand but... isn't it still simply the reason why the slope isupward because of the temperature rise??

Would anyone advise?
