An adiabatic turbine operates with inlet steam at 2.00 MPa and 600 C and outlet steam (100% vapor) at 0.10 MPa and 99.6 C. How

1. An adiabatic turbine operates with inlet steam at 2.00 MPa and 600 ºC and outlet steam (100% vapor) at  0.10 MPa and 99.6 ºC. How much work does the turbine produce? (Answer in kJ/kg and with correct sign.)
   1. 
      
2. One mole of carbon dioxide (CO₂) reacts to form carbon monoxide (CO) and oxygen (O₂).  Assuming that all of these gases are ideal, what is the enthalpy of this reaction at 1298 K (Δ_rHº₁₂₉₈)? (Answer in kJ/mole with correct sign.)
