Definition
Elementary steps are individual processes within complex reactions that occur in one single event or stage.
Analogy
Consider elementary steps as individual dance moves within an entire choreography routine. Each move happens independently and contributes to completing the whole performance.

The reaction described [O3(g) + O(g) → 2O2(g)] is the decomposition of O3. With an addition of NO, the reaction proceeds in two elementary steps and a mechanism is shown: [Step 1: O3 + NO → NO2 + O2 (slow)] [Step 2: NO2 + O → NO + O2 (fast)]. Which is the rate law?
