Assuming that in free-radical polymerization the rate coefficients for initiator dissociation, propagation and termination can be replaced by the appropriate Arrhenius expressions kd = Ad exp (−Ed /RT) kp = Ap exp (−Ep /RT) kt = At exp (−Et /RT) calculate the changes in the rate of polymerization and the degree of polymerization caused by increasing the temperature of polymerization of styrene in benzene, initiated by azobisisobutyronitrile, from 60 °C to 70 °C given that: Ep = 34 kJ mol−1 Et = 1 kJ mol−0 1 Ed = 126 kJ mol−1 Assume that the concentration of monomer and initiator and the values of f and q remain unchanged when the temperature is increased.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
