Answer:

D. Zn(s)

Step-by-step explanation:

For a spontaneous reaction to occur, the reduction potential of the reacting substance should be greater than that of Fe3+.

5. Among the given options:

a. Fe2+(aq) - This is the reduced form of iron (Fe3+), so it is not likely to react spontaneously with Fe3+.

b. I2 - Iodine does not have a lower reduction potential than Fe3+, so it is not likely to react spontaneously.

c. Hg(l) - Mercury is not likely to react spontaneously with Fe3+ as it does not have a lower reduction potential.

d. Zn(s) - Zinc has a lower reduction potential than Fe3+, indicating that it can undergo a spontaneous reaction with Fe3+
