A chemical process involves heating a reaction mixture to produce a desired product. The reaction occurs at a constant pressure of 1 atmosphere. The initial volume of the reaction mixture is 10 liters, and the initial temperature is 25°C. During the reaction, the volume of the reaction mixture increases to 15 liters, and the final temperature is 75°C. The heat capacity of the reaction mixture is 4.18 J/(g°C). a) Calculate the change in volume (∆V) during the reaction. b) Calculate the change in temperature (∆T) during the reaction. c) Calculate the total heat (Q) absorbed or released during the reaction. d) Determine whether the reaction is endothermic or exothermic based on the heat value obtained in part c.
