An exothermic reaction is a chemical reaction that produces energy, usually in the form of heat. An endothermic requires an input of energy to proceed. Answer and Explanation: Learn more about this topic: Combustion Reaction |...
How is enthalpy used to predict whether a reaction is endothermic or exothermic? Calculate the enthalpy change for the following reaction using the bond energies and Lewis structures shown below. 2NH3 (g) rightarrow N2 (g) + 3H2 (...
The () that maintains the high-level structure of protein is an endothermic reaction (entropy-driven), that is, it strengthens with increasing temperature and weakens with decreasing temperature.A.Hydrogen bonding.B.Electrostatic interaction.C.Van der Wa
N2(g)+3H2(g)---> <---2NH3(g) deltaH=92kJ. What is the enthalpy of formation of ammonia from its elements? If these are the exact terms that the question was expressed in, then you have no choice but to put down option (E.) even though you know it to be wrong/unrealistic...
N2(g) + 3H2(g) arrow 2NH3(g); Delta H = -92.2 kJ The overall reaction in commercial heat packs can be represented as 4Fe(s) + 3O2(g) to 2Fe2O3(s), Delta H = -1652 kJ. How much heat is released when 4.00 moles of ...
The cracking reaction is very endothermic, and requires a large amount of heat. Another problem is that reaction quickly fouls the Silica (SiO2) and alumina (Al2O3) catalyst by forming coke on its surface. However, by using a fluidized bed to slowly carry the catalyst upwards, and then ...
In an endothermic process, the internal energy of the system: a. remains unchanged b. It cannot be determined. c. increases d. decreases Given the reaction: NH_3(g) + O_2(g) to NO(g) + energy, in what direction will the reaction shift, if you: a) remove O_...
What bonds or attractive forces have to be broken in order for ethane to dissolve in water? Is the breaking of these bonds exo or endothermic? Which of the following molecules if any would be held together by hydrogen bond, ...
