Firstly I apologise if this is the wrong forum, and would ask for forgiveness in advance.
My issue is as follows: I wish to make several calculations using the spreadsheet, or possibly make a program to help out with the process.
So what I would like to do is make multiple guesses and have the calculator make a few calculations based on my guesses.
The equations I wish to use are Antoine's equation and Raoult's law (chemistry).
The Antoine equation is: ln(Piº)=Ai-((Bi)/(Ci+T(K)))The Antoine constants for two components are A, B, C for cell number 1 & to for respective component.
I wish to guess the given temperature until Raoults law is true:
xi*Piº=y_i*P, where P is known, either x_i/y_i is known and Sum(x_i)=Sum(y_i)=1.
To solve Piº for each component I will normally use solve(ln(Piº)=Ai-((Bi)/(Ci+T(K))),Piº) for a guessed T, for both components, check if the sum=1 and if not, iterate with a new guess. This process can be tedious and I'd like to shorten it.
Code:
Lets says y_i is given and x_i sought (and the relevant temperature is also sougt)
The solution is as follows: Guess T ► Find Piº ► solve Xi ► Check if Sum(Xi)=1 ► [No?] ►Guess another T
►[Yes?] Great, we have found relevant T
Now how would I go about doing this on the CX CAS using spreadsheets to do the calculations for me?
What I have tried so far (mind you the X1 and X2 columns are not full calcs, just calcs for Piº, but they give errors)
Thank you in advance,
