The diagram is an example of which of the following? Butane
O aldehyde
O alkane
O alkene
O alkyne

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

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.
