Using for next loop please solve code

1. Vapor pressure calculation (Chemical Engineering Application) (15 points) The Redlich-Kwong (RK) equation predicts the true behavior of a gas better than the ideal-gas law by including molecular interactions that occur at high pressures. The equation was formulated by Otto Redlich and Joseph Neng Shun Kwong and relates the temperature, pressure and volume of gases as shown below RT a p = (v-b) v(v+b)VT where R2T2.5 0.427 Pc RT b 0.0866 Pc C Where R gas constant, L atm/g mol K V molar volume, L/g mol T = temperature, K p = pressure, atm Te critical temperature, K Pe= critical pressure, atm a, b RK equation constant a. Draw a flowchart and write a VBA Sub Program to calculate the pressure using the RK equation for a temperature range of 500 to 800 K. Show transcribed image text 1.
