Given only the following data, what can be said about the following reaction?
3h2(g) + n2(> 2nh3(g) δh=-92kj
a.) the enthalpy of products is greater than the enthalpy of reactants
b.) the total bond energies of products are greater than the total bond energies of reactants
c.) the reaction is very fast
d.) nitrogen and hydrogen are very stable bonds compared to the bonds of ammonia

The correct answer is B the total bond energies of the product is greater than the total bond energies of the reactants.

Explanation:

3H2+N2=2NH3

This reaction is an endothermic reaction that means that reaction consume heat energy.

   Due the above reaction is endothermic the enthalpy change of the reaction is negative(-ve).

  During endothermic reaction the total bond energies of the product is greater than the total bond energies of the reactants.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the answer is 1 i believe
