The correct Answer is:
To solve the question, we need to analyze both statements given in the problem. ### Step 1: Analyze Statement 1 Statement 1 claims that if the standard oxidation potential (SOP) of a substance is less than -1.23 V and the overvoltage is 0 V, then its oxidation in an aqueous solution is not possible at 298 K. - The standard reduction potential (SRP) of water is +1.23 V, which means the oxidation potential of water is -1.23 V (since oxidation is the reverse of reduction). - For a substance to be oxidized in an aqueous solution, its SOP must be greater than -1.23 V (i.e., it should be less negative than -1.23 V). - Therefore, if the SOP of the substance is less than -1.23 V, it cannot be oxidized because it is more negative than the oxidation potential of water. **Conclusion for Statement 1:** True. ### Step 2: Analyze Statement 2 Statement 2 states that the standard reduction potential (SRP) of water is +1.23 V. - This is incorrect because the standard reduction potential of water is actually -1.23 V when considering the oxidation reaction (2H₂O → O₂ + 4H⁺ + 4e⁻). - The correct statement should be that the SRP of water is -1.23 V for the reduction of water to oxygen. **Conclusion for Statement 2:** False. ### Final Conclusion - Statement 1 is true. - Statement 2 is false. Thus, the answer is that Statement 1 is true and Statement 2 is false.
