What is an exothermic reaction? The energy of the reactants is lower than the energy of the products. Absorbs energy in the form of heat. The energy of the reactants is lower than the energy of the products. Releases energy in the form of heat. The energy of the reactants is higher than the energy of the products. Releases energy in the form of heat. The energy of the reactants is higher than the energy of the products. Absorbs energy in the form of heat.

Reaction Description of Ethanol: In this section, you will describe a reaction related to the production or use of the compound, ethanol. You must include the following: 1)Type of reaction—Describe the general class of reaction (combustion, acid/base, redox, etc.).2)Heat of reaction—Provide the amount of heat that must be added or removed from this reaction at the relevant temperature and whether this reaction is exothermic or endothermic.3)All products, reactants, and catalysts—Include a balanced equation with all states of participants.4)Special considerations—Document the safe operating range of this reaction, safety considerations, and side reactions that may produce unwanted products.5)Summary of other possible reactions—Provide either another reaction to produce the compound or an alternate use and its reaction.

Chemical reactions occur when molecules or atoms collide in a way that the bonds between atoms break and new bonds form. Breaking the bonds of the reactants requires energy, whereas bond formation releases energy. Select the true statements regarding energy changes during a reaction. When the activation energy is high, the reaction rate is fast. If the heat of reaction, AH, is positive, the energy of the products is lower than the energy of the reactants and the reaction is exothermic. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. The energy of a collision between atoms or molecules must be greater than or equal to the activation energy, Ea, for bonds to be broken. Increasing the concentration of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. The activation…

During an experiment a student mixed two chemicals together and noted that the beaker felt warm to the touch after the reaction was complete. In the experiment, the chemicals would be classified as the From this observation, the student concluded that the reaction was A. Which of the following energy pathway diagrams represents the chemical reaction from the student's experiment? Ep (kJ) Select one: OA OB 150 125 100 + and the beaker would be classified as the Reaction Coordinate and that the resulting change in enthalpy (AH) would have a B. 125 E 100 Reaction Coordinate Ep (kJ) 150 ◆ value.

The energy of the reactants is shown on the following energy diagram. On the right side of the energy diagram, draw a horizontal line segment to indicate the energy of the products. Draw a vertical double-headed arrow (↕) on the graph that corresponds to the value of ΔH for the reaction.
