Reaction Rate vs Rate of Consumption/Formation

Postby VivianaHF2L » Fri Mar 08, 2019 2:07 am

In the third question of the sixth edition book, it had three parts one asks for the reaction rate and the other two asks for the rate of formation. What is the difference between these two because the book does not really give an equation for the reaction rate just for the rate of formation.

I think the rate of consumption is the rate that the reactants are being used up. The rate of formation is the rate that the products are being formed.

During that problem, I think you are supposed to interpret the reaction rate as a unique rate to find the rate of consumption/formation.

Also, unique rate can be found in terms of the rates of formation or consumption by dividing by the coefficients in the equation (the rate of consumption has to have its sign flipped to make it positive).

The reaction rate or rate of reaction is the speed at which reactants are converted into products.
The formation rate is the rate that products are being formed.
The two definitions are very similar.
