6. (20 pts) Air from inside a house enters a steady-flow heat exchanger with a volume flow rate of 200 m³/min at 15°C, 100 kPa and leaves the heat exchanger at 35°C. This heat exchanger is located inside the air handler of a house heat pump system and receives heat from the heat pump. The heat pump receives heat from air outside the house that acts as a heat source at 10°C. Assume air has constant specific heats at the values for 300 K. Assume air has constant specific heats evaluated at 300K. (a) Determine rate of heat supplied to the air in the heat exchanger $Q_H$, in kW. (b) Assuming the air in the heat exchanger acts as a heat sink having an average temperature of 25°C, determine the minimum power supplied to the heat pump, in kW.

to the next question prevents changes to this answer. Question 2 10 points The elementary, irreversible, liquid phase reaction: A+B--> 2C is carried out in an isothermal, isobaric 40-liter batch reactor with 20 kg of catalyst. The reactor is filled with 30 moles of A and 30 moles of B. The catalyst decay is first order with respect to activity. If the reactor is operated at 300 K, calculate concentration (mol/liter) of product C after 30 minutes. Additional Information: $k = 3.35 \text{ liter}^2/\text{(mole-kg cat-min)} \text{ at } 450 K$ $k_d = 0.1 \text{ min}^{-1} \text{ at } 300 K$ $\frac{E}{R} = 1245 K$ $C_{PA} = 50 \text{ J/mole K}$ $\Delta H_R = -10,000 \text{ J/mole at } 400 K$ $\frac{E_d}{R} = 650 K$ $C_{PB} = 30 \text{ J/mole K}$ $C_{PC} = 40 \text{ J/mole K}$
