← ScienceWhich outcome arises when reactant concentration oscillates near chemical equilibrium in polymerisation?
A)Polymer chain length distribution broadens✓
B)Reaction exothermic potential decreases
C)System entropy instantaneously maximizes
D)Activation energy barrier shifts upwards
💡 Explanation
Broad chain distribution results because oscillatory concentrations impact the chain growth via the kinetic chain length mechanism; therefore, a wider range occurs, rather than a single length because other factors have less direct influence on uniformity.
