question 40

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.
