My friend and I did a zinc and copper sulfate reaction. He calculated an order of reaction of 1, a year ago I calculated an order of reaction of 2 (same reaction), a few days ago How is this even possible? Can the same reaction have two different orders?
The IUPAC defines that a reaction is of order α with respect to a substrate A only when the macroscopic rate can be expressed by a power law: r = k[A]α[B]β… [1]. For reactions with more complex rate laws, as catalytic reactions usually have, it is necessary to identify a...
