The video tutorial explains the concept of the rate determining step in reaction mechanisms, using the decomposition of hydrogen peroxide as an example. It describes how the slowest elementary step dictates the overall reaction rate and introduces the concept of intermediates and catalysts. An hourglass analogy is used to illustrate how the rate determining step functions, emphasizing that the reaction rate depends on the slowest step, similar to how sand flows through the narrowest part of an hourglass.
