Creat a spread sheet or matlab file with the following functionality: a/ The utility shoud use th P(in MPa) and T(in K) to calculate the ideal gas molar volume (in cm3/mol) at a reference state and two other states labeled ‘state1' and ‘state2'. All three states should be easy to edit/specify. (b) Add functionality to calculate the ideal gas enthalpy for n-butane at ‘state1' and ‘state 2' relative to the reference state, using the full form of the heat capacity polynomial. Program this in a manner that will be easy to edit for other compounds by using variable names and/or cells(if Excel) for the heat capacity coefficients. Also, calculate the ?H between the two states using the enthalpy values (not another integral). Set the reference state to 298.15K and 0.1 MPa. Set state 1 to 378.15K, 0.5 MPa, state 2 to the 463.15K, 2.5 MPa,. (c) Provide handwritten examples of the equations programmed for H and V. Provide a printout of your results.
