Discussion Section Question: 1) Oxides of sulfur are important in atmospheric pollution, arising in particular from the burning of coal. Use the thermodynamic data in the Table below to answer the following questions: 0 205.1 -241.8 188.7 -296.8 248.2 -395.7 256.8 -814.0 156.9 a) In air, the oxidation of SO 2 can occur: . Calculate the standard Gibbs energy change at T=298K Solution: b) Find the ratio of equilibrium partial pressures of SO 3 (g) to SO 2 (g) in air at T=298K. Assume the partial pressure of O 2 (g) is 0.21 atm. Solution: c) In the atmosphere, SO 3 (g )reacts with H 2 O(g) to form sulfuric acid H 2 SO 4 (g). In the atmosphere at equilibrium and at T=298K the partial pressure of H 2 O(g) is 0.031 atm. Find the ratio of the partial pressure of H 2 SO 4 (g) to SO 3 (g) in air at

Unformatted text preview: T=298K. Solution: 2) Adenosine triphosphate (ATP) is an important compound produced by the conversion of glucose to CO 2 and H 2 O in the respiratory system. The hydrolysis of adenosine triphosphate at T-298K and P=1 atm produces adenosine diphosphate (ADP) and inorganic phosphate P i : . a) Calculate Δ G when [ATP]=0.01M, [ADP]=0.0001M, and [P i ]=0.10M. What is the maximum work produced by the hydrolysis of one mole of ATP? Solution: The maximum work produced is . b) Suppose transport of three moles of Na + across a cell membrane requires 40 kJ of work. If the work required for this transport is derived from hydrolysis of ATP, what ratio of [ADP] to [ATP] is required to achieve this transport? Assume [P i ]=0.1M. Solution:...
