Consider we have chemical that is well described by the virial equation (see below). PV/RT = 1 + B(T)/V Find a relationship for (partialdifferential inP/partialdifferential T)_sat as a function of delta _vap H, T and compressibility of gas (Z). Consider the vapor-liquid transition and a model for the vapor pressure in the form below. Determine an expression for delta _vap H that is a function of T and Z. ln P6sat(T) = A_1 - A_2/T - A_# lnT We are interested in a chemical at 348K that delta_vap H-31.6 kJ/mol and has a molar liquid volume for a saturation of 9.65 times 10^-2 m^3/mol. For the vapor pressure equation above, A_1 = 43.552, A_2 = 5622.7 and A_3 = 4.70504. Using this information, find the value of the second virial coefficient at 348K.
