At what temperature will the following be spontaneous? Delta H = -18 kJ and Delta S = -60 J/K Delta H = +18 kJ and Delta S = +60 J/K Delta H = +18 kJ and Delta S = -60 J/K Predict the sign of Delta S for the reaction HCI(g) doubleheadarrow H + (aq) + Cl-(aq) Using appendix 4, calculate Delta S, Delta H and Delta G for the following reaction: CH_4 (g) + 2O_2 (g) doubleheadarrow CO_2(g) + 2H_2O(g) For the reaction: 2NO_2 (g) doubleheadarrow N2O_4(g) The value of Delta H = -58.03 kJ and Delta S = -176 J/K. a. Calculate Delta G at 298K b. Assuming Delta H and Delta S are unaffected by temperature, at what temperature is Delta G = 0? Calculate Delta G for an acid ionization if Ka = 4.5 times 10^-3 at 25 degree C
