In this assignment, we will consider 1 mole of N2(g) which is in a closed container. In state 1, the temperature is 25°C and the pressure in the container is 10 bar.We assume that N2 behaves like an ideal gas and that Cp,m(g) = 29.125 J mol-1K-1, and is independent of temperature. 1) How large will a) the volume work, b) the heat and c) the change in enthalpy of N2 be if, starting from state 1, the volume of the container was changed in a reversible and isothermal manner so that the pressure in the container drops to 1 bar? 2) How big will a) the volume work, b) the heat and c) the change in enthalpy of N2 be if, again starting from state 1, the volume of the container was changed in a reversible and adiabatic way so that the pressure in the container drops to 1 bar? 3) a) Explain what reversible means in tasks 1) and 2) b) state what the change in the entropy of the universe is in tasks 1) and 2). 4) How large will a) the volume work, b) the heat and c) the change in enthalpy of N2…
