Answer:

d. ΔG°rxn is positive and the reaction is spontaneous in the reverse direction.

Explanation:

∵ ΔG°rxn = - RTlnK.

When lnK = negative, ΔG°rxn = - RT(- Ve).

∴ ΔG°rxn is positive.

When ΔG°rxn is:

negative: the reaction is spontaneous in the forward direction.

zero: the reaction is at equilibrium.

positive: the reaction is non-spontaneous in the forward direction and spontaneous in the reverse direction.

So, the right choice is:

d. ΔG°rxn is positive and the reaction is spontaneous in the reverse direction.
