A decomposition reaction was studied on three different surfaces. The activation energy on each surface is shown in the table. Which surface represents the best heterogeneous catalyst if the activation energy of the uncatalyzed reaction is 452 kJ/mol? A. Copper
B. Tungsten
C. Uncatalyzed
D. Platinum

please help. my only try

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

i believe the answer is a.

the answer is a and have a great day

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
