Examine Trials 1, 2, and 3: observe the rate at 20°C (14.2), 37°C (28.5), and 55°C (4.1). Describe the trend before reading choices.
Elimination Strategy: Option A says 'decreases monotonically' (false). Option B says 'increases monotonically' (false). Option D contradicts the data.
Looking at Trials 1-3 (pH constant at 7.0): At 20°C the rate is 14.2; at 37°C it peaks at 28.5; at 55°C it drops precipitously to 4.1. This represents an initial increase due to collision kinetics, followed by a steep drop caused by thermal...
