### 15.85

Hello, I'm having trouble on HW 15.85, which asks us to draw a proposed structure for the activated complex. Could anyone explain what the proposed structure is and how to figure it out?

Example: "Rate= k[I]2[Ar] (Products are I2 and Ar; the role of the Ar is to remove energy as the product forms.)"
Answer: [I...I...Ar] (with the transition state symbol as a superscript)

Thank you.

A transitional state is an arrangement of molecules or atoms that can either go to form products or back to reactants. When you want to draw such structure, just connect all atoms or molecules with dashes (lines are used to connect atoms within a molecule).
