Estimate the activity and activity coefficient for $\mathrm{CS}_2$ at $x_{{ }^{C S_2}}=0.722$ using the data in Table for both a Raoult's law and a Henry's law standard state.

Solution

Verified**We are given the following data:**

$\begin{align*} &x_{CS_2}=0.722\\ \\ \end{align*}$

**Required:**

$\cdot$ The activity and activity coefficient for $CS_2$ for both Raoult’s law and Henry’s law standard state.

**Steps involved in solving the question:**

$\cdot$ We will be using a table to get the value of partial and pure vapor pressure of $CS_2$.

$\cdot$ Then we will be using relation to evaluate the activity and activity coefficient for Raoult’s law.

$\cdot$ Then we will be getting the value of $K_{CS_2}$ from Example Problem 9.9 on page 230.

$\cdot$ Finally we will be using relation to evaluate the activity and activity coefficient for Henry’s law standard state.
