What effect does the decomposition of ozone into oxygen have on entropy and enthalpy?

Options

  1. AEntropy increases, and enthalpy remains unchanged
  2. BBoth entropy and enthalpy increase
  3. CBoth entropy and enthalpy decrease
  4. DEntropy increases, and enthalpy decreases

Correct answer

B. Both entropy and enthalpy increase

Step-by-step solution

The decomposition of ozone into oxygen results in an increase in entropy (∆S is positive) and liberation of heat (∆H is negative), which leads to both entropy and enthalpy increasing.
