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.

What is a zero order reaction and how does it relate to the concentration of ammonia?

Describe the process that occurs when ammonia molecules bind to the platinum surface.

How does the decomposition of ammonia into nitrogen and hydrogen gases illustrate the concept of zero order reactions?

Explain why the rate of reaction does not change even when the concentration of ammonia is increased in case 2.

What is the significance of the number of ammonia molecules bound to the platinum surface in a zero order reaction?
