Decomposition of NH3 and Zero-Order Reactions : A Closer Look

The video tutorial explains the concept of zero order reactions, using the decomposition of ammonia as an example. It describes how the rate of reaction is independent of the concentration of ammonia, as the reaction rate is determined by the number of ammonia molecules bound to a platinum surface. Two cases are considered: one with low ammonia concentration and another with increased concentration. Despite the increase, the reaction rate remains unchanged, illustrating the principle that zero order reactions are unaffected by reactant concentration.
