Define the activity relative to a pure liquid standard state

Reference no: EM13340950

Solutions of hexane and heptane may be considered to be ideal. At 25°C, the vapor pressure of pure hexane is 20.3 kPa and the vapor pressure of pure heptane is 6.08 kPa The activity relative to a pure liquid standard state is defined as the ratio of Pi (the vapor pressure of a species over the solution) to Pi * (the vapor pressure of the pure liquid). By how much does the chemical potential of hexane change if the mole fraction of hexane is changed from 0.380 to 0.250, ? If you can not obtain a numerical answer, or do not trust your result, decide if the chemical potential will increase or decrease and briefly justify your answer. this is the answer G: = -1040 J /mol, but anyone can show me how to solve this question G= -1040 J/ mol
