4. Draw a free energy reaction coordinate diagram for both a generic endergonic and a generic exergonic reaction (label each). Make sure to label the x- and y-axes. Now label where reactants and products should go on the figure. Draw something that illustrates the free energy change for each reaction. Now write something like the following next to your figures: “reactants <—> products”. a. What do the reaction coordinate diagrams have to do with the text you just wrote? b. What...
2. The hydrolysis of ATP is the cell’s most commonly used exergonic reaction when performing energy coupling. Explain energy coupling, why it is necessary, and how the hydrolysis of ATP fits into the process. Use vocabulary words such as “endergonic,” “exergonic,” “spontaneous,” and “nonspontaneous.” (8 points) BIOLOGY CELLULAR RESPIRATION/PHOTOSYNTHESIS Please answer in one-two paragraphs
5 of 15 A reaction is non-spontaneous. What can you conclude about the reverse reaction? O It is spontaneous. It must be exothermic O It must have an increase in entropy O It is in equilibrium. 6 of 15 Based on the AG calculation, a student determined that a synthesis reaction should be spontaneous. When the student tries out the reaction, however, nothing happens. Which explanation is most plausible? O the student probably made a mistake in the calculation O...
1. Which of the following processes are spontaneous or non-spontaneous? a. 2 H2(g) + O2(g) → 2 H 0(2) b. Recharging a battery without plugging it in. C. Salt dissolving in water d. Freezing a popsicle at room temperature 2. For the following equilibrium constant values, indicate whether the process is spontaneous or nonspontaneous AND whether the value of ArxnGº is greater than less than or equal to zero by circling the appropriate response. Equilibrium Constant Value Is the reaction...
UT WIL US: Laplan your answer. ne tollowing as spontaneous/non-spontaneous/cannot tell, and explain. Also, provide a real example for each. A reaction that is a. exothermic and becomes more positionally random b. exothermic and becomes less positionally random c. endothermic and becomes more positionally random d. endothermic and becomes less positionally random
v For each of the following reactions, explain why they are spontaneous or non spontaneous based on the change in entropy of the reaction 2N20 (0) -> O2 (8) --> 2N2 (8) Decrease in the number of mole and phase change from gas to aqueous solutic A both decrease entropy N2 (g)+ 3H2(g) -> 2NH3 (8) B Decrease in the number of mole decreases entropy + CaCO3 (8) -> CaO (5) + CO2 (g) Increase in the number of mole...
16. Gibb's Free Energy is a. the spontaneous energy of a reaction b. the chemical energy that can be used for performing work c. the non-spontaneous energy of a reaction d. the amount of activation energy needed for a reaction to start Based on the ∆G calculation, a student determined that a synthesis reaction should be spontaneous. When the student tries out the reaction, however, nothing happens. Which explanation is most plausible? the student probably made a mistake in the...
Your classmate is excited to tell you about something they just learned. There’s a toxin named ouabain that was used by East Africans to make poison arrows. “And guess what-ouabain kills people by blocking the sodium/potassium pump that we learned about in BILD 1!” But your classmate is confused about something. “The sodium/potassium pump moves sodium and potassium ions against the concentration gradients, in the opposite direction of how the ions would normally go. But in class we said that...
