please help with 1 and 2 thank you!

1. (5pt) Determine the changes in enthalpy in a stepwise manner (hypothetical path design). (a) the nitrogen when the temperature is changed from 65C to 20C at 1atm. (b) the nitric oxide when the temperature is changed from 20C to 65C at 1atm. 2. (5pt) A liquid mixture of 27mol% acetone and 73mol%n-hexane is vaporized from 10 to 95 C and from 1 to 3atm. Calculate the specific enthalpy change in kJ/mol for both compounds and the required heat for a 1 mole solution. Use the stepwise method (path design) for specific enthalpy and then determine the heat flow. Include the followings: (a) Drawing/labeling, (b) General energy balance equation (c) A list of the assumptions/findings (d) Simplified form of the energy balance equation, (e) Calculation procedure in detail
