The equilibrium relationship for a chemical reaction is given by: (cc + x) K = (ca-2x)2 (cb-x) If K=0.16, ca=42, cb=28, cc=4: (a) For what values of x is the function undefined? (b) In order to avoid these singularities, rewrite the function as a polynomial. (c) Plot the function over a range of x values to show the roots. (d) Use the MATLAB fzero command to find each of the roots. (e) Use the MATLAB roots command to find all roots of the polynomial.
