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