Answer:
C. Chemical Bonds are broken
Explanation:
A chemical reaction occurs when chemical bonds are broken.
Chemical reactions occur when chemical bonds between atoms are formed or broken.
Hope this helps :)
I think that the answer is Rate=k[H2O2][I-]
Answer:
D
Explanation:
The potential energy curve of a system of atoms define the potential energy of the atoms with respect to the inter-nuclear separation. The minimum point of the curve represents the equilibrium bond length of the bond.
The energy of the system depends on the distance between the two interacting atoms.
Looking at the potential energy curve for hydrogen molecule in option D, we can assert that a chemical bond indeed exists between the two atoms of hydrogen and the minimum point of the curve is the equilibrium bond length of the bond.
