Show that for a reversible adiabatic process, PVY is constant for an ideal gas. Note: ● ● ● For ideal gases use the ideal gas law: PV = RT Cp You also need to assume that y = Cy is constant. The assumption that y is constant for an ideal gas is equivalent to the assumption that the heat capacities are constant. This is the only way that the ratio and the difference Cp - Cy Cy can both be constant = y and Cp - Cy=R). In reality, Cp and Cy increase with temperature, but their ratio y is less sensitive to the temperature than the heat capacities themselves.

PART 4 PLEASE
The efficient design of chemical plants depends on the designer's ability to access and use the heat output in one process to supply another process. The standard enthalpy of reaction for N2(g) + 3H2(g) -> 2NH3(g) is -92.22 kJ/mol. What is the change in enthalpy when kJ. 3 sig. number in exponential format, e.g. 3.45E5, 5.32E- (a) 1464.5 kg of N2 (g) is consumed? 6, -4.44e3,.... (b) the change in enthalpy when 1308.5 kg of NH3 (g) is formed. kJ. 3 sig. number in exp. format.

Consider the expression: dS=dT - VadP. Suppose that water has ß = 4.53x10-5 atm¯¹, V = 18 cm³/mol, C = 18 cal/deg-mol, and a = 2.0 x10 deg¹. Compute the decrease in temperature which occurs if water at 25 °C and 1000 atm pressure is brought reversibly and adiabatically to 1 atm pressure.
Knowing that the molar heat capacity at constant pressure of CO₂ has the form Cp,m = (a + b + c/T²) J mol-¹K-¹, where a= 44.22, b= 8.79 x 10-³ K-¹, and c= -8.62 x 105 K 2,calculate how much heat can absorb 1.5 moles of this gas when the temperature is increased from 25°C to 150°C.

Calculate the change in entropy (in J/K) when 400 mL of water at 33.8 ⁰C is heated to 55 ⁰C at constant pressure. Specific heat capacity of water at constant pressure is 4.183 J/g-K. Density of water at different temperature is presented (use this table only). Answer Format: [2 decimals
Formulate a combustion reaction of benzene, liquid C6H6 My answer: 2C6H6 + 15O2à 12CO2 + 6H2O In experiments performed with a bomb calorimeter, it was found that the change of the internal energy in this combustion process is equal to: ΔU=-3264 [kJ x mol-1] Assuming that the temperature during the experiment is 298 degrees Kelvin, calculate the percentage difference between the change in enthalpy and the change in energy

0.418 J K¯'g¬1 288 298 308 318 Temperature (K) Part A Using the protein DSC data, calculate the enthalpy change between T = 288 K and T = 318 K. Give your answer in units of kJ per mole. Assume the molar mass of the protein is 13000. grams per mole. Hint: You can perform the integration of the heat capacity by estimating the area under the DSC curve and above the baseline. This can be done by dividing the area into small rectangles and summing the areas of the rectangles. Express your answer to two significant figures and include the appropriate units.
