In radical chain polymerization the quantity given by the 'rate of monomer depletion, divided by the rate of propagating radical formation' is called

(a)kinetic chain length

(b)propagation efficiency

(c)propagation rate constant

(d)polymerization time

Answer

Answer: A ✓ checked by 4AB · confidence high
