Part C The pressure, temperature and volume of a system change differently during the process of isothermal expansion. Indicate whether each quantity increases (I), remains constant (C), or decreases (D). Your answers should describe the changes of pressure, temperature, and volume (in that order). Separate your answers with commas (e.g., I,C,D means pressure increases, temperature remains constant, and volume decreases). Part D What is the work W done by the gas as it expands isothermally from V0 to fvV0? Express...

Question 10 1 pts Consider the equilibrium: CH, (g) + H2O(g) + 206 kJ CO(g) + 3H2(g). Which of the following disturbances will NOT cause the system to shift to the right to reestablish equilibrium? The volume decreases. The temperature increases. The partial pressure of CO decreases. All of these will cause the system to shift to the right. • The partial pressure of CH4 increases.

During a constant pressure, nonflow (closed system) process, a gas loses 103 BTUs of heat to the surroundings while it's volume changes from 2.2 ft3 to 0.7 ft3. If the temperature of the gas decreases by 7 oF and the system contains 3.3 lbm of gas, find the absolute pressure of the system in lbf/in2. cV for this gas is 0.229 BTU/lbm-oF. (Hint: For this process, ∆U = mcV∆T even though the process is not carried out at constant volume). State...
