Your task is to obtain the solution by analytical and numerical methods and compare it with the perturbation solution.

Verify the following analytical solution for the concentration distribution and the gradient at the gas-liquid interface:

\[\begin{equation*}c=c_{1}+\left(1-c_{1}+\frac{p_{1}}{K+1}\right) \frac{\sinh [\beta(1-x)]}{\sinh \beta}+\frac{p_{1}}{K+1}(x-1) \tag{14.56}\end{equation*}\]

and

\[\begin{equation*}p_{1}=-\frac{\left(1-c_{1}\right)(1+K)}{1+(K / \beta) \tanh \beta} \tag{14.57}\end{equation*}\]

These equations can be used to compare the numerical results as well as perturbation results. Perform such a comparison for values of \(M\) and \(K\) in the text and verify the results in Table 14.2.
