b) The petrochemical sector is witnessing significant growth due to the growing demand for downstream products from various end-use industries such as construction, pharmaceuticals, and automotive. In your Final Year Design Project (FYDP) report, predict the fugacity and fugacity coefficient for iso-Butane that has a high demand for the formation of isobutylene at 40 C (313.15 K) at 9 bar. Properties of pure species iso-Butane are given by: Ai= 13.8254, Bi = 2181.79, Ci= 248.87, w = 0.181, Tc= 408.1 K, Pc= 36.48 bar, Zc= 0.282, Vc= 262.7 cm /mol, B = -0.5617, B = -0.3842, and R = 83.14 cm bar/mol K
