please explain step by step.

You need to obtain a simple vapour pressure correlation for water that works in the vicinity of 180C(10C higher and 10C lower). The only information ou have are the critical parameters and the Lee-Kessler Charts (The van der Naals EOS may not be used for calculations for this question). a) For a pure component that is at its boiling temperature at a [3] certain pressure, name the three properties (excluding temperature and pressure) of the co-existing phases that are equal at the phase boundary. b) Estimate the enthalpy of vaporisation at 180C. [8] c) Use this information and determine a vapour pressure correlation using the Clapeyron equation (given below) as a starting point. All information not given in the appendix needs to be derived from first principles. Assume the vapour phase can be approximated as ideal. All parameters in the correlation should be in SI units. dTdPsat=T(VVVL)HVHL If you do not have an answer for part (b), or do not trust your answer, assume the heat of vaporisation at 180C is 20000J/mol. Note, this value is not the correct answer for part (b)
