Based on each paragraph, there are TWO (02) questions. Each question has FOUR options (A), (B), (C) and (D). ONLY ONE of these four options is the correct answer. Paragraph for Question Nos. 26 and 27 Consider the stereoisomer of iso-leucine labelled as below: NH2 OH O CH3 (P); NH2 OH O CH3 (Q); NH2 OH O CH3 (R); NH2 OH O CH3 (S) Consider the following data to answer the questions posted: (i) Set molar Gibb’s free energy of ‘P’, o 1 m G 0 kJ mol .   (ii) The equilibrium constant   eq K for epimerization of (P) has the value of 1.38 (at 374 K). (iii) Epimerization of (R) into (Q) follows first order kinetics with rate constant ‘k’ (at 374 K) = 5 1
