When deploying the Steady State Approximation (SSA) to resolve a complex multi-step chemical rate la — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The core kinetic assumption of the SSA dictates that a wildly unstable intermediate is consumed nearly instantly upon generation. Consequently, its macroscopic absolute concentration remains practically negligible and perfectly constant, allowing the differential to be algebraically set to $\frac{d[I]}{dt} \approx 0$.
