Question

Look at the chemical reaction C2H6 + 137 kJ → C2H4 + H2.

How does the chemical energy of C2H6 compare to the chemical energy of C2H4 and H2?


The chemical energy of C2H6 is greater than the chemical energy of C2H4 and H2.

The chemical energy of C2H4 and H2 is greater than the chemical energy of C2H6.

The chemical energy of C2H6 and C2H4 and H2 are equal because energy is conserved.

Answer 1

The correct answer is: The chemical energy of C2H6 is greater than the chemical energy of C2H4 and H2.
