Oxygen reacts with the dipeptide glycylglycine [C4H8N2O3(s)] to form urea [CH4N2O], carbon dioxide and water: 3O2(g) + C4H8N2O3 (s)  CH4N2O (s) + 3CO2(g) + 2H2O(l) At STP, solid glycylglycine has the following thermodynamic properties: = -491.5 kJ/mol =...

Nicotine is not only bad for you (ahem!), but it also acts as a base in aqueous solution: Kb = 7x10-7 at 298K. i) Find G per mol of nicotine acting as a base in aqueous solution at 298K. ii) Find the pH of the solution if the initial [nicotine] = 0.80 M....
