### What does unique rate of reaction mean?

What does the textbook mean when it asks us to find the unique rate of reaction? What is the process of solving for it?

Very intriguing questing Nathan Tran. I am glad you asked this to further facilitate the conversation of Kinematics.

The unique rate is a rate of a reaction divided by its stoichiometric coefficient. A unique rate will be the same for each reactant or product but the product will be a negative value.

I am so glad that you have recognized this. I make an active goal to engage in pragmatism, especially in the realm of kinematics. Are you saying you divide the rate of A by the stoichiometric coefficient of A?

The unique raate of the reaction can be solved for using this formula: -(1/a)(d[a]/dt)

Conceptually it is average reaction rate adjusted for the stoichiometric coefficient so that the consumptions of each product and reactant are equal.

"Unique reaction rate is the average reaction rate divided by the coefficient in a chemical equation."

The unique rate of each reactant and product are the same in a reaction because the changes are with regards to each species' coefficient. The average and instantaneous rates of each reactant and product in a reaction may differ.
