Exothermic Which of the following are true? Choose all that apply. The reaction is exothermic . The energy of the products is lower than the energy of the reactants. The value of Ea in the presence of a catalyst would be lower than 205 kJ. The value of Ea at higher temperatures would be lower than 205 kJ. E is positive . Entropies of ionic solids tend to increase as the attractive forces between the ions decrease, because vibrational motion is easier. Recall that attractive forces between ions increase as charge increases, and decrease as size increases. Which of the following statements best describes the energy changes involved when chemical bonds are formed? There are no overall energy changes because energy can be neither created nor destroyed. Energy may be absorbed or released when bonds are formed depending on the atoms that are present in the bond. Energy is required to form bonds in the products of a reaction. That energy is stored in the bonds. When chemical bonds are formed, the system becomes more stable and energy is released. 100 mL of water at 25 o C and 100 mL of alcohol at 25 o C are both heated at the same rate under identical conditions. After 3 minutes the temperature of the alcohol is 50 o C and the temperature of the water is 35 o C. After five minutes the temperature of the alcohol is 65 o C and the temperature of the water is 50 o C. Which liquid received more heat as it warmed to 50 o C? Select the answer with the best explanation.
