What mass of aluminum metal can be produced per hour in the electrolysis of a molten aluminum salt by a current of 25 A?
Chapter 14: Chemical Kinetics Kinetics is the study of reaction rates and how much of the concentration of the product changes with time Products concentration tends to increase while Reactants concentration tends to increase Concentration is shown with “” Collision theory Reactant particles must collide Reactant must come into contact in the proper orientation (has to be lined up the right way) Reactants must have a sufficient amount of energy to react Surface Area and the effect on reaction rate Ex. If there was an iron nail in a bottle of oxygen the reaction would occur slowly because it is only reacting with the outer layer of molecules. If the iron nail was replaced with iron wool the reaction rate is higher because there is more molecules throughout the wool. Orientation and the effect on reaction rates The second part of the collision theory says that molecules have to be in the right orientation to react There are certain enzymes that aid in this process. Enzymes hold the molecule in a certain orientation so that other molecules can collide and react. Energy and the effect on reaction rate Higher temperature increases the energy the molecule has. The higher the energy the faster the molecule moves. The faster the molecule moves the higher chance of a collision. Higher chance of collision means there is a higher chance of having an effective
