Benzoic acid, C;HsO:H, is typically used as a çalibrant for determining the specific heat of bomb calorimeters. It combusts via the following unbalanced chemical reaction: C,H5O2H (s) + 02(g) → CO2 (g) + H2O(1) 3. For this experimental setup and reaction, the constant volume heat flow is known to be gy = -26.979 kJ. Over the course of the reaction, the temperature rose from 19.863 °C to 22.540 °C. Calculate the heat capacity, Cou, for this calorimeter in kJ °C-!.
Q3) Thermodynamic Processes- 2.0 mol of a diatomic ideal gas undergoes a process in which it is compressed very slowly from state a (V. = 3.0 m³, P, = 1000 Pa) to state b (V, = 1.0 m³), in such a way that the system maintains thermal equilibrium with its surroundings at all times. P (Pa) 3000 2000 A. Find the change in internal energy during the process. 1000 B. Find the final pressure of the gas. 1 3 4 V(m³) C. Find the work done by the piston on the gas during this process. (Hint: Since Pis not constant during this process, it doesn't come out of the integral. Use the ideal gas law to find an expression for Pin terms of constants and the integration variable V) D. So what's the work done by the gas on the piston during this process? E. How much heat – if any - was transferred between the gas and surroundings during this process? Did heat flow from the gas to the surroundings or from the surroundings to the gas? Explain your reasoning. F. At the end of the process, is the average…
(a) Suppose that attractions are the dominant interaction between gas molecules, and the equation of state is p = nRT/V – n2a/V2. Determine the work (W(non-ideal gas)) of reversible, isothermal expansion of such a gas from initial volume V (initial) = 20.0 L to final volume V(final) = 40.0 L if n = 2.00 mol, T = 300 K, and a = 3.621 atm-L2/mol2. Watch your units. (b)Determine the work (W(ideal gas) of reversible, isothermal expansion of an ideal gas from initial volume V (initial) = 20.0 L to final volume V(final) = 40.0 L if n = 2.00 mol and T = 300 K. (c) Show the difference W(non-ideal) – W(ideal). If all your calculations are done correctly, this result shows you the effect of attractive interaction between gas particles on the work done by the system.
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.
