An ideal gas undergoes the following Carnot Cycle. It starts in a chamber of volume .0065 m³ and temperature 345 Kelvin and pressure 630 kPa (state 1). It is allowed to expand isothermally to a volume of .01066 m³ (state 2) while heat is added to the gas. Then it expands adiabatically to a volume of .01784 m³ (state 3). Then, it is compressed isothermally to a volume of V_f m³ (state 4) while heat is extracted from the gas. Finally, it returns to its initial state in an adiabatic process. (The gamma of the gas, γ = 1.28, C_v = 3.5R).

How much heat is added in the 1^st isothermal process and the efficiency of this engine?

a.)1.878 kJ, 11.2%

b.) 2.029 kJ, 11.2%

c.) 2.029 kJ, 13.6%

d.) 2.334 kJ, 13.6%

e.) 2.334 kJ, 15.8%
