Which of the following statements is correct for a spontaneous polymerization reaction ?
- A \(\Delta \mathrm{G} \lt 0, \Delta \mathrm{H} \lt 0, \Delta \mathrm{S} \lt 0\)
- B \(\Delta \mathrm{G} \lt 0, \Delta \mathrm{H}\gt0, \Delta \mathrm{S}\gt0\)
- C \(\Delta \mathrm{G}\gt0, \Delta \mathrm{H} \lt 0, \Delta \mathrm{S}\gt0\)
- D \(\Delta G\gt0, \Delta \mathrm{H}\gt0, \Delta \mathrm{S}\gt0\)
Answer & Solution
Correct Answer
(A) \(\Delta \mathrm{G} \lt 0, \Delta \mathrm{H} \lt 0, \Delta \mathrm{S} \lt 0\)
Step-by-step Solution
Detailed explanation
Hint : \(n A \rightarrow A_n\) During spontaneous polymerisation reaction number of particles decreases, hence entropy decreases. Being spontaneous \(\Delta \mathrm{G}\) of the reaction is less than zero. \(\Delta \mathrm{G}=\Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{S}\) To…
