13. Indicate whether the following statements are true or false. If false, correct the statement so that it is true. a. A change in enthalpy for exothermic chemical reactions is negative. b. An endothermic reaction is one in which enthalpy is absorbed by the system from the surroundings. c. Condensation of water vapor is an example of an endothermic process. d. Heat, q, and enthalpy, AH, are state functions, meaning they depend on the path taken, and q = AH....

An adiabatic heat exchanger is one for which no heat is exchanged with the surroundings. All of the heat lost by the hot stream is transferred to the cold stream in this adiabatic process. In a proposed process, propane gas enters a continuous adiabatic heat exchanger at 45 °C and 265 kPa and exits at 255 °C. Superheated steam at 300 °C and 7.0 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at...

4. True or False a. During an endothermic reaction, energy is absorbed from the surroundings b. The amount of heat needed for a reaction to occur is dependent on the path used to determine the products c. Metals tend to have higher specific heat values than H20 5. Calculate the change in heat, q, when 75 grams of aluminum is cooled from 200°C to 50 °C. Specific heat of Al is 0.90 (J/g °C)
