XE-FMCQ2 marksNeeds review
The propagation step of a free radical copolymerization is represented by the following possible reaction steps:
P1:
, rate constant =
P2:
, rate constant =
P3:
, rate constant =
P4:
, rate constant =
where,
and
are two monomers and
and
are the active radicals of
and
, respectively.
(
) represents the rate constant of each step as shown above.If the reactivity ratios of
and
are expressed as:
and
, respectively, and feed mole ratio,
is expressed as
(where,
and
are the concentrations of
and
, respectively), the probability of the reaction P2 is ______.Your answerChoose one option.
