Researchers studied four catalysts for a chemical reaction. They recorded reaction rate (mol/sec) at 25°C and at 50°C: Catalyst A, 0.4 (25°C), 0.7 (50°C); B, 0.6, 1.5; C, 0.5, 0.9; D, 0.3, 1.6. The team argued that for high-temperature applications, peak reaction rate at 25°C is <em>not</em> a reliable predictor of which catalyst will perform best at 50°C. The data most uniquely supporting this claim is ______
Which choice most logically completes the text using the data above?
- A
Catalyst B's highest 25°C rate of 0.6.
- Bcheck_circle
the rank reversal: Catalyst D had the lowest rate at 25°C (0.3) but the highest at 50°C (1.6); Catalyst B led at 25°C but was overtaken at 50°C.
- C
the average rate across catalysts.
- D
Catalyst A's 50°C rate of 0.7.
Explanation
"25°C performance does not reliably predict 50°C performance" requires showing rank reversal. Choice B captures this directly.
