Which of the following statements best describes the entropy change (Delta S) during the reaction shown below? 2NH_3(g) rightarrow N_2(g) + 3H_2(g) A. Delta S 0 D. sign of Delta S depends on the temperature at which the change takes place E. there is no entropy change in this system The enthalpy change during a reaction is positive. Which of the following statements must be false? A. The reaction is endothermic B. The reaction is exothermic C. The reaction is product-favoured D. The reaction is reactant-favoured E. The reaction is rapid Questions 36 and 37 concern a particular reaction where: Delta H = - 32 kJ Delta S = - 98 J K^-1 Assuming that enthalpy and entropy do not vary with temperature, at what temperature will the reaction be at equilibrium? A. - 330 K B. 330K C. 330 degree C D. 0.33 K E. 0.33 degree C If the reaction mixture is held at a temperature of 0 degree C, will the reaction occur spontaneously or not? A. The reaction is spontaneous at all temperatures B. Delta G = - 32 kJ, reaction is spontaneous C. Delta G = - 32 kJ, reaction is non spontaneous D. Delta G = - 5.2 kJ, reaction is spontaneous E. Delta G = - 5.2 kJ, reaction is non spontaneous
