Below are four definitions. Which of these most accurately describes the concept of chemical potential?a. The chemical potential represents the probability that a chemical reaction will occur.b. The chemical potential quantifies the change in internal energy when a molecule is added to a system at constant volume and entropy.c. Chemical potential is the heat transferred from (or to) a system when a chemical reaction occurs.d. The chemical potential is the greatest amount of work that a system can do as a result of a complete chemical reaction. Explain each alternative
What is a strategy that someone could use if they are not sure about how energy moves between the system and the surroundings in a reaction?
c. Draw a potential energy diagram for the formation of NO₂(g): N₂(g) +20₂(g) → 2NO2(g). AHreaction = 66.2 kJ/mol. Label the graph with "Reactants," "Products," "AHreaction," and "Ea
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.
1. The relationship as regards the transfer of heat between the system and the surrounding is INVERSELY proportional. Check the CAPITALIZED WORD(S) if it makes the statement correct. If it does, choose TRUE. If not, choose FALSE. A. TRUE B. FALSE 2. Frying an egg is an ENDOTHERMIC reaction. Check the CAPITALIZED WORD(S) if it makes the statement correct. If it does, choose TRUE. If not, choose FALSE. A. TRUE B. FALSE
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
Which of the following statements about the storage of energy using chemical systems are correct? Mark all that are true. A. When energy is stored in a system where Q > K, energy is released from storage when the forward reaction occurs. B. Storing energy in a chemical system requires taking the system away from equilibrium. C. If AG° is negative, the forward reaction will always release energy and the reverse reaction will always store energy. D. The energy available by carrying out the forward reaction will change unless we take some additional action to hold Q constant.
The dissolving of ammonium nitrate is often used in an instant cold pack used to relieve swelling. If this process is an endothermic reaction, i.e. absorbs heat, then why does it feel cold to the touch instead of hot?
Use the References to access important values if needed for this question. When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. Thermometer Cardboard or In the laboratory a general chemistry student finds that when 14.72 g of BaBr2(s) are Styrofoam lid dissolved in 101.00 g of water, the temperature of the solution increases from 22.80 to 25.27 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.82 J/°C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of BaBr2(s) in kJ/mol. Reaction occurs in solution. Assume the specific heat of the solution is equal to the specific heat of water. AHdissolution = kJ/mol
As the temperature is increased, which kinds of reactions become more product-favored? a. All reactions that result in an decrease in entropy. b. Only those that are exothermic and result in an decrease in entropy. c. Only those that are endothermic and result in an increase in entropy. d. Only those that are exothermic and result in an increase in entropy. e. All reactions that result in an increase in entropy.
Using the chart determine if the net reaction will overall be exothermic or endothermic show work
Nature favors exothermic reactions because after such a reaction a. energy previously held in many particles is now concentrated in a few, resulting in a temperature fall. b. energy previously concentrated in a few particles is now dispersed over more particles in the system. c. energy previously concentrated in a few particles is now dispersed over more particles in both the system and the surroundings. d. energy previously concentrated in a few particles is now dispersed over more particles in the surroundings. e. energy previously held in many particles is now concentrated in a few, resulting in a temperature rise.
