Ical Equations (continued) Identify which of the reactions below is endothermic, and explain
how you know.
AH = –1625 kJ
1. 4Fe(s) + 302(g) → 2Fe2O3(s)
2. NH4NO3(s) + NH4+ (aq) + NO3- (aq)
AH= 27 kJ

The answer is b because a,c,and d are opinons

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
