Problem 1: Steam at 200 °C and 10 bar is cooled under constant pressure until it becomes saturated liquid. a) What is the final temperature? b) How much heat is removed from the steam? c) Calculate the work involved in this process, if any. Problem 2: a) Water at 1 bar, 20 °C is heated at const P to produce steam with quality 95%. What is the amount of heat? b) What is the final state if the amount of heat is 2100 kJ/kg?
In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. T..
