Question

At 100°C and 1 atm, 36 mL of pure water takes 100 seconds to evaporate from a vessel, when an electric heater which delivers 806 watt power is connected to the vessel. Now, select the CORRECT statement(s) about this process:

q p ​ = 806 × 100 = 80600 J , Δ H v ​ a p = 2 80600 ​ = 40300 J / m o l = 40.3 k J / m o l Δ S v ​ a p = T B ​ . pt Δ H v ​ a p ​ × 2 = 373 40300 ​ × 2 = 216.08 J / K Since the system is at equilibrium, Δ G = 0 , and the vapor pressure of H₂O(l) is P e ​ x t = 1 a t m = K P ​ . Therefore, Δ G ∘ = 0 .
