1. Define each of the following for a chemical reaction: Favored Non-favored Exothermic Endothermic AH AE
One proposed source of clean energy is the combustion of hydrogen in the presence of oxygen. This reaction releases a significant amount of energy, and the only product of the reaction is water. The balanced chemical equation is shown here: 2H₂(g) + O₂(g) →→→ 2H₂O(g) + energy
Consider a hypothetical chemical reaction: A+B → C+D (In this equation A, B, C and D stand for some unknown chemical formulas.) Here is an energy diagram for the reaction: energy (kJ/mol) 400 300- 200- 100. 0 A+B C + D reaction coordinate Use the energy diagram to answer these questions. What is the heat of reaction? Is the reaction exothermic or endothermic? Are the reactants (A+B) or the products (C+D) more chemically stable? kJ/mol O Exothermic Endothermic Neither Reactants (4+B) O Products (C+D) Neither
Consider the reaction shown: H+ 12-2 HI + 2.2 kcal We can say that this reaction is and that the sign of AH is a. endothermic; negative; energy is being release from the reaction b. endothermic; positive; energy is being put into the reaction c. exothermic; positive; energy is being put into the reaction O d. exothemic; negative; energy is being release from the reaction e. exothermic; neither positive nor negative
In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
