Question

which statement describes the reaction represented by n2(g)+3h2(g)->2nh3(g)+93kj?

Endothermic because energy is absorbed
Endothermic because energy is released
Exothermic because energy is absorbed
Exothermic because energy is released

Answer 1

What is an exothermic reaction?

Answer 2

Exothermic :Chemical reaction accompanied by the release of heat.
Endothermic: Chemical reaction accompanied by the absorption of heat.

Answer 3

In exothermic reactions the enthalpy change is negative, is your enthalpy change negative?

Answer 4

To determine enthalpy you can look at the bonds broken and formed

Answer 5

Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.

Answer 6

So i would go with the last answer given. :)
