Vedclass · Answer

(A) For a spontaneous reaction, the Gibbs free energy change must be negative, i.e.,$\Delta G In a polymerization reaction, many monomer units combine to form a single polymer chain $(n A \rightarrow A_n)$.This process leads to a decrease in the number of particles and an increase in order, resulting in a decrease in entropy, i.e.,$\Delta S Using the Gibbs-Helmholtz equation: $\Delta G = \Delta H - T \Delta S$.Since $\Delta G For $\Delta G$ to remain negative, the enthalpy change $\Delta H$ must be negative and its magnitude must be greater than the magnitude of $T \Delta S$, i.e.,$\Delta H < 0$.
