- Balance each of the following redox reactions occurring in acidic solution. Part A VO2 (aq) +ClO2 (aq) →VO2+(aq) + ClO2(g) Express your answer as a chemical equation. Identify all of the phases in your answer. = ΑΣΦ ? A chemical reaction does not occur for this question. You have already submitted this answer. Enter a new answer. No credit lost. Try again.arrow_forwardFor a particular reaction, AH° = −16.1 kJ/mol and AS° = −21.8 J/(mol·K). Assuming these values change very little with temperature, at what temperature does the reaction change from nonspontaneous to spontaneous in the forward direction? OT= Is the reaction in the forward direction spontaneous at temperatures greater than or less than the calculated temperature? less than greater than Karrow_forwardA particular reaction has a ΔG‡ of 37.0 kJ mol-1. In the presence of an enzyme, the same reaction has a ΔG‡ of 5.70 kJ mol-1. Calculate the value of ΔΔG‡ in kJ mol-1.arrow_forward
- discuss the following statement: “Whether the ΔG for a reaction is larger, smaller, or the same as ΔG° depends on the concentration of the compounds that participate in the reaction.”arrow_forwardRefer to Model 10.1 and answer the question that follows What is free energy? What is its symbol?arrow_forwardConsider the analogy of the jiggling box containing coins that was described on page 85. The reaction, the flipping of coins that either face heads up (h) or tails up (T), is described by the equation h ↔ T, where the rate of the forward reaction equals the rate of the reverse reaction.a. What are ΔG and ΔG° in this analogy? b. What corresponds to the temperature at which the reaction proceeds? What corresponds to the activation energy of the reaction? assume you have an “enzyme,” called jigglase, which catalyzes this reaction. What would the effect of jigglase be and what, mechanically, might jigglase do in this analogy?arrow_forward
- Calculate the value of AG, if the value of AH is +1200 Kcal/mol, AS is +60 Kcal/mol, and the reaction takes place at 300 K. Once you calculate the value of AG, you can predict the reaction is +16800 Kcal/mol, non-spontaneous/unfavorable - 16800 Kcal/mol, spontaneous/favorable -19200 Kcal/mol, spontaneous/favorable + 19200 Kcal/mol, non-spontaneous/unfavorablearrow_forwardUnder what conditions might a reaction be endothermic but exergonic? Explain.arrow_forwardWhich of the following is TRUE under the following conditions: the enzyme concentration is 2.5 nM, substrate concentration is 75 nM, the KM = 150 nM, and the Vmax = 20 nmol/min a) The rate of the reaction is 20 nmol/min! b) The rate of the reaction is between 10 nmol/min and 20 nmol/min. c) The rate of the reaction is 10 nmol/min. d) The rate of the reaction is below 10 nmol/min. e) The rate cannot be determined from the above information.arrow_forward
- Consider the following chemical equation whose delta(G) = 9kcal/mol: AC + BD ---> AB + CD what are the reactants and what are the products is this reaction spontaneous? How do you know? Is energy released or consumed by this reaction? If an enzyme, which catalyzes this reaction is added, what will happen to delta (G) If this reaction is coupled to another reaction, whose delta(G) is -12 kcal/mol, what will be the net delta(G) value? will the overall reaction be spontaneousarrow_forwardIn the reaction ATP + glucose → ADP + glucose-6-phosphate, ΔG° is -16.7 kJ/mol. Assume that both ATP and ADP have a concentration of 1 M and T = 25°C. What ratio of glucose-6- phosphate to glucose would allow the reverse reaction to occur?arrow_forwardCan the thermodynamic property Δ G° be used to predict the speed of a reaction in a living organism? Why or why not?arrow_forward
