The reaction below is exothermic: 2SO2 (g) O2 (g) 2SO3 (g) Le Chtelier's Principle predicts that will result in an increase in the number of moles of SO3 (g) in the reaction container.

If a certain battery supplies 1.0×108 electrons per second to the negative terminal and the battery contains 7.00 moles of electrolytic solution (which means the solution contains 7.00 moles of hso4), what fraction of the solution undergoes a chemical reaction each second

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?
