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.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
