Question

find the value of delta H in j/mol

Propane gas at 1 bar and 35°C is compressed to a final state of 135 bar and 195°C. Estimate the molar volume of the propane in the final state and the enthalpy and entropy changes for the process. In its initial state, propane may be assumed an ideal gas. (For data, use the table for the characteristic properties of pure species.) The values of Rare given in the table below. (Include a minus sign if required.)
