Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g) 1. Calculate the number of grams of CO that can react with 250 g of Fe2O3.

2. Calculate the number of grams of Fe and the number of grams of CO2 formed when 250 grams of Fe2O3 reacts.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
