Which Statement About the Reaction Below, Where En = Ethylenediamine $\leftrightarrow$

Multiple Choice

Which statement about the reaction below, where en = ethylenediamine (H₂NCH₂CH₂NH₂) , is not correct?
Cr(NH₃) ₆³⁺ + 3en $\leftrightarrow$ Cr(en) ₃³⁺ + 6NH₃

A) The reaction is product-favored because the entropy of the system increases.
B) The Lewis basicity of the amino groups in en is comparable to that of the ammonia molecules.
C) The reaction is reactant-favored because the concentration of ammonia on the right side is higher than the concentration of en on the left side.
D) The reaction enthalpy is small because the Cr-NH₃ and Cr-en bond strengths are very similar.
E) Both Cr(NH₃) ₆³⁺ and Cr(en) ₃³⁺ have an octahedral coordination geometry and a coordination number of 6.
