  • $\begingroup$ It isn't. The answer options are 1, 2, 3 and 4; there is no option for d. Also, this is a simple question to write out in legible fashion; no need for difficult-to-read sideways photograph. $\endgroup$ – airhuff Mar 13 '17 at 7:56

Ea = (delta)H + RT i guess that ends the confusion. Now you can adjust the last term and have all 3 cases as possible
