I am hesitant to answer BECAUSE bond energies are used for gas phase reactions only and this certainly is not a gas phase reaction. However, to continue,
dHrxn= BE reactants - BE products
dHrxn = 3040 - (1564 + 1009) = 3040 - 2573) = 467
+ means the reaction is endothermic so A
Ammonium nitrate dissolves in water via the following reaction:
NH4NO3(s) → NH4+(aq) + NO3-(aq)
The bond energies of the compounds in the reaction are as follows:
NH4NO3 = 3040 kJ/mol
NH4+ = 1564 kJ/mol
NO3- = 1009 kJ/mol
How much total energy does the reaction have, and how will the environment change when the reaction occurs?
A: 467 kJ/mol; lose heat
B: −467 kJ/mol; gain heat
C: 467 kJ/mol; gain heat
D: −467 kJ/mol; lose heat
