Which outcome occurs when a platinum catalyst contacts hydrogen peroxide?

💡 Explanation

The catalytic decomposition of hydrogen peroxide occurs because the platinum catalyst offers an alternate reaction pathway with lower activation energy, therefore H₂O₂ rapidly decomposes to water and oxygen rather than remaining as hydrogen peroxide.
