Question

Show your work- No work, U reuit Tungsten hexacarbonyl, W(Co)s) can be decomposed to W(s) and CO(g) at high temperature. What is work involved when two (2) moles of W(CO)s(s) are decomposed at 150 °C and 1 bar pressure 1) T T423K ! (A) +21.1 kJ (D)-10.5 kJ 2) What areq and U when 2.5 moles of a perfect gas is expanded reversibly and isothermally from 3.0 L to L at 35°C (A) q = 0 kJ and U =-12.1 kJ (B) q =-12.1 kj and AU-0 q = +12.1 kj and U = 0 (D) q = +12.1k] and AU =-12.2 kJ For problem 3 and 4: Consider five (5) moles of an ideal gas with Cv, m 12.47 Jmol-K-1 is expanded adiabatically against a constant external pressure of 1.00 bar. The initial temperature and pressure of the gas a 325 K and 2.50 bar, respectively. The final pressure is 1.25 bar. 3) The work, w, for this process is approximately: (A) +4.93 kJ (B) -4.93 k (C) + 5.00 kj (D)- 3.00 kJ The Enthalpy change, H, for the process is approximately: -8.21 k B) 9.00k 4) (A) -8.21 kJ (B)-9.00 k) (C) + 8.21 k (D) 5.00 k
