The three liquid solutions listed below are each at 300K and atmospheric pressure. 25 kg of pure water, 40 kg of pure sulfuric acid, and 77 kg of 22 wt% sulfuric acid. They can be mixed using one of two methods. #1: If they are mixed isothermally, how much heat is generated in kJ? #2: The mixing is carried out in two steps. First the pure sulfuric acid and the 22 wt% solution are mixed, and the total heat of mixing ALL THREE solutions is removed. Next, the pure water is added adiabatically. What is the temperature in Kelvin of the intermediate solution formed in the first step. H/kJ (kg solution)¹ 300 200 100 O -100 -200 -300 -400 Copyright © McGraw-Hill Education.
