For [M(NH₃)₆]²⁺ + 3en ⇌ [M(en)₃]²⁺ + 6NH₃, measured values are ΔH° = −6 kJ mol⁻¹ and ΔS° = +60 J K⁻¹ mol⁻¹. Assume temperature-independent values over the range. Which statements are correct?
Options:(select one or more)
Answer:
A, B
Solution:
ΔG° = ΔH°−TΔS° = −6−300(0.060) = −24 kJ mol⁻¹; at 400 K it is −30, more negative. Both negative ΔH° and positive ΔS° favour the product. Actual equilibrium also depends on the reaction quotient, including the third power of en and sixth power of NH₃, so standard favourability does not imply complete conversion at arbitrary concentrations.
