The correct Answer is:
To determine the reducing power of the metals X, Y, and Z based on their standard electrode potentials, we can follow these steps: ### Step 1: Understand Standard Electrode Potential Standard electrode potential (E°) indicates the tendency of a metal to be reduced. A more negative value means a greater tendency to oxidize, which correlates with a higher reducing power. ### Step 2: List the Standard Electrode Potentials - Metal X: E° = -1.2 V - Metal Y: E° = +0.5 V - Metal Z: E° = -3.0 V ### Step 3: Compare the Electrode Potentials To determine the reducing power, we need to identify which metal has the lowest (most negative) standard electrode potential, as this indicates a higher tendency to oxidize and thus a higher reducing power. - Metal Z has the lowest E° (-3.0 V). - Metal X is next with E° (-1.2 V). - Metal Y has the highest E° (+0.5 V). ### Step 4: Determine Reducing Power Order Based on the standard electrode potentials: - Metal Z (E° = -3.0 V) has the highest reducing power. - Metal X (E° = -1.2 V) has moderate reducing power. - Metal Y (E° = +0.5 V) has the lowest reducing power. ### Conclusion The order of reducing power is: Z > X > Y ### Final Answer The reducing power of the metals is: Z > X > Y. ---
