Done In Excel The Redlich-Kwong equation of state (RK EOS) is:P =RTaV-b √TV (V + b)where P is the pressure, I the absolute temperature, and R the gas constant. The coefficientsa and b are given in terms of Tc and Pc for the fluid, bya = 0.42748R² T 2.5/P and b = 0.08664R Tc/PcYou will find the values of V for which P = 9.46 bar (= 946kPa) at T=350K for n-butane,which has Tc = 421.5K and Pc = 3796kPa. The smallest Vis the liquid phase, while thelargest is the vapor phase (the intermediate value is unstable).a) From the RK EOS, what must be the dimensions of b? Verify that the formulas for a andb are dimensionally consistent with the RK EOS. (Hint: from the ideal gas EOS, PV andRT have the same dimensions.) With P in Pa and T in Kelvin, what are convenient unitsfor R, b, and V?b) Plot P versus V, for V ranging from 0.0001 to 0.1 m^3/mol. Use a log scale for V.Construct the V table to be equally spaced on a log scale, with 20 points per decade. Todo this, start with a table of log10 V values: -4, -3.95, ...-1. Compute and plot P in MPa.
