Unique Average Rate

Postby TiffanyL1G » Wed Mar 06, 2019 9:38 pm

Can someone explain in simpler terms what the unique average rate is, why we use it, when to use it, and when not to use it? What qualities affect the rate and what qualities do not?

The unique average rate of a reaction is just the rate of a reaction but put in terms that the rate of change of a specific reactant or product of the reaction are all equal to each other. Dividing by their coefficients and making sure to make the rate of change of the reactants negative, each individual rate relative to each individual reactant/product of the reaction should be equal to each other.

so the unique average rate of each product/reactant is the same exact thing?

Yes, the unique average rate of reaction for each product/reactant is the same, as long as you know the change concentrations of each substance, the corresponding coefficient, and the change in time.

What's an example problem of when we would have to use the unique average rate?

Also, the book says that the unique average rate "does depend on the coefficients used in the balanced equation." Why is this the case? I thought unique average rate of change takes care of the stoichiometric coefficient differences between the reactions and products?
