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

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
