26PRACTICE PROBLEM
Hydrogen peroxide decomposes quickly into water and oxygen gas in the presence of a platinum catalyst. The decomposition reaction takes place in two steps:
Step 1: Pt + H2O2 → H2O + Pt(O) (slow)
Step 2: Pt(O) + H2O2 → Pt + O2 + H2O (fast)
Identify the molecularity of each individual step.
