Kevlar (C₁₄H₁₀N₂O₂) is used in various applications from tires to body armor due to its high strength-to-weight ratio. The polymer is produced from the monomers paraphenylene diamine (C₆H₈N₂) and terephthaloyl (C₈H₄C_l2O₂) by the following reaction:

(a) What type of polymerization does the above reaction represent?

(b) Assuming 100% efficiency, calculate the weight of terephthaloyl chloride required to completely combine with 1 kg of paraphenylene diamine.

(c) How much Kevlar is produced?
