When 2 moles of NH3(g) react with N2O(g) to form N2(g) and H2O(g) according to the following equation, 880 kJ of energy are evol

Naily [24]

Answer:

The reaction is an exothermic reaction .

The value of q is -880 kilo Joules.

Explanation:

Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system. The total enthalpy of the reaction $(\Delta H)$ comes out to be negative.

According to reaction, 2 moles of ammonia when reacts with 3 moles of nitrous oxide to give 4 moles of nitrogen gas and 3 moles of water vapor, along with release of 880 kJ of heat energy.

Since, heat is evolved during the course of reaction which means that reaction is an example of Exothermic reaction.

$2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g),\Delta H=-880 kJ$

The reaction is an exothermic reaction .

The value of q is -880 kilo Joules.
