Write a balanced equation for the combination reaction that takes place when iron(III) oxide is formed from its constituent elements.

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.

the correct answer is a

just took the test and its a negative cl`

may be too late but may others : )
