For all questions involving calculations, write out any equations used in the solution. (a) Dinitrogen tetroxide (N204) is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide (NO2): N2O4 (g) 2 2NO2(g). For this this equilibrium, A:H° = 58.02 kJ (mol N2O4)1 and A,S° = 176.1 JK- (mol N204) and are assumed to be constant with temperature. Write a DIMENSIONLESS equation for the equilibrium (i) constant K of this reaction. Assume the mixture behaves ideally. (ii) Determine the standard Gibbs energy for the reaction at 298.15 K. (111 Calculate the equilibrium constant at 298.15 K. (iv) Name which species will predominate at 298.15 K. (v) Calculate the temperature at which neither species will predominate.
