Answer: C) Both are made up of monomers that are linked by covalent bonds
Explanation: Polymers are large molecules which are formed by combination of small repeating units called as monomers.
Natural polymers are found in nature such as cellulose whereas synthetic polymers are synthesized in laboratories such as Nylon 6,6.
All the polymers, whether natural or synthetic are made up of monomers and are joined by covalent bonds.
The relation between rate constants at different temperatures, temperature and activation energy is known as Arrhenius equation
<u>Arrhenius equation</u>
For two temperatures
Where
Ea = ? = activation energy
k1 = 3.36 × 10⁴
T1=344 k
k2=7.69
T2=219K
R= gas constant = 8.314 J /molK
Putting values
Ea = (-69.69)/(-0.00166) = 41981.93 J/mol
Or
Activation energy is 42.0 kJ /mol
