When the rate of one compound is know, the rate of another compound is calculated through rate-to-rate comparison.

Stoichiometric Rate Calculations

Concept #1: If the rate of decomposition of H2 is 1.54 M/min at a particular time, what would be the rate of formation of N2 at that same time.

 2 NO (g) + 2 H2 (g) → N2 (g) + 2 H2O (g)

Practice: The formation of alumina, Al2O3, can be illustrated by the reaction below: 

4 Al (s) + 3 O2 (g) →  2 Al2O3 (s). 

At 750 K it takes 267 seconds for the initial concentration of Al2O3 to increase from 6.18 x 10-5 M to 5.11 x 10-4 M. What is the average rate of Al?
