The standard molar enthalpy formation of ammonia, NH3(g) is -45.92 kJ. 1/2 N2(g) + 3/2 H2(g) ==> NH3(g) If 5,0 mol of NH3(g) is mixed with 5.0 mol of H2, which of the following statements is TRUE for this reaction condition? Select one: O a. 459.2 kJ is released in the formation of the NH, for these amounts of reactants. O b. 45.92 kJ is released for the formation of 10.0 mol of NH3:(g). O. Hz is the limiting reactant and 153 kJ of heat is absorbed in the formation of 3,33 mol NH3. O d. Nz is the limiting reactant and 153 kJ of heat is released in the formation of 10.0 mol NH3. O e. 153 kJ is released in the formation of the NH3 for these amounts of reactants.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
