The statement that is untrue concerning a reversible reaction is The reaction always spends equal time in the forward and reverse direction. The answer is letter B. The reset of the statements are true concerning the reversible reaction.
Which letter (a-f) represents potential energy (ΔH) of the reactants?
Answer:
1) Which letter (a–f) represents potential energy (ΔH) of the products?
2) Which letter (a-f) represents potential energy (ΔH) of the activated complex?
3) Which letter (a-f) represents potential energy (ΔH) of the reactants?
Explanation:
The graph ploted represents the changes in the chemical potential (stored) energy for the reaction X + Y → Z as long as it evolves from reactants to products.
The left side of the graph shows the potential energy of the reactants, X and Y, when the reaction has not yet occurred.
Thus, the letter (a) is the potential energy of the reactants.
Moving from left to right you see that the potential energy increases, until a maximum. The maximum is when the reactants (X and y) have reacted up to an intermediate stage, in which there exists a transition state featured by an activated complex whose structure is half-way between the reactants and the products.
Thus, the letter (c) represents the potential energy of the activated complex.
At the far right of the graph, the reaction has gone to completion, the activated complex ends the transition state and the final products are formed. Thus, the letter (e) represents the potential energy of the products (Z).
All those energies are measured with respect to the same base line (the x-axis).
The attached graph has some labels added to help to identify the 3 stages: reactants, activated complex, and product.
Potential energy of products, reactants and activated complex in an energy profile diagram are displayed right end, left end and at the highest point of the diagram, respectively. However, the corresponding letters (a-f) would depend on the specific diagram.
In general, when you look at an energy profile diagram, the potential energy (ΔH) of the products is usually represented by the energy level of the products on the right side end of the diagram, which could be any of the letters a-f but depends on the specific diagram given. Similarly, potential energy (ΔH) of the reactants can be represented by the energy level of the reactants on the left end of the diagram. The potential energy (ΔH) of the activated complex, also known as the transition state, is usually the highest point on the diagram, indicating the highest energy level.
It's important to keep in mind that these are general guidelines for interpreting an energy profile diagram. The actual answer to your question (potential energy, activated complex, and reactants would depend on the specific diagram you're looking at.

Answer:
behavioral observation scale
Explanation:
According to my research on different methods for providing feedback, I can say that based on the information provided within the question Joseph should use a behavioral observation scale. This feedback method measures the level of performance and frequency of certain behaviors. In this situation this feedback method would be the easiest and most accurate method of providing feedback.
**Even though no answer choices were provided this method is the most used in these types of situations.**
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer: Option (c) is the correct answer.
Explanation:
According to Le Chatelier's principle, when a system is in equilibrium for a long time then it will change its concentration, temperature, volume or pressure to attain a new equilibrium that partly counteracts the applied change.
Since it is given that reaction is exothermic therefore, according to Le Chatelier's principle increase in temperature will be opposed so that reaction can proceed in the forward direction. Therefore, temperature has to be decreased to carry the reaction in forward direction.
Whereas pressure has to be increased so that reaction will shift to the forward side where there are less number of molecules.
Thus, we can conclude that to increase the yield of the products for the given reaction decrease the temperature and increase the pressure.
Answer is: The atomic size of the chlorine ion is larger than the size of the chlorine atom.
Covalent radii of chlorine atom (Cl) is 0.099 nm and ionic radii of chlorine anion (Cl⁻) is 0.181 nm.
Difference between an chlorine atom and chlorine anion is the number of electrons that surround the nucleus.
Chlorine atom has 17 electrons and chlorine anion has 18 electrons.
