Explanation Reason for correct option: Correct option (e) Effect of temperature on the spontaneity is given below, ΔH o ΔS o ΔG o sign + + + or - The above process is spontaneous only at high temperatures . Statement given as ΔG < 0, ΔH > 0 and ΔS > 0 . The phase transition of water from liquid to vapor is endergonic reaction and spontaneous reaction so the value of free energy should be negative and the values of enthalpy change and entropy change (created by more disordered gaseous molecules) are should be positive. Hence, the correct option (e). Reason for incorrect options: Incorrect options are (a), (b), (c) and (d)

Give the product of the bimolecular elimination from each of the isomeric halogenated compounds. Reaction A Reaction B. КОВ CH₂ HotBu +B+ ко HOIBU +Br+ Templates More QQQ Select Cv Templates More Cras QQQ One of these compounds undergoes elimination 50x faster than the other. Which one and why? Reaction A because the conformation needed for elimination places the phenyl groups and to each other Reaction A because the conformation needed for elimination places the phenyl groups gauche to each other. ◇ Reaction B because the conformation needed for elimination places the phenyl groups gach to each other. Reaction B because the conformation needed for elimination places the phenyl groups anti to each other.
