# Free Energy of a Non-Equilibrium Synthesis of Sulfur Trioxide

CHEM-YHFNYI

Consider the reaction below.

$$2\textrm{SO}_2(g) + \textrm{O}_2(g) \rightleftharpoons 2\textrm{SO}_3(g)$$

Given $\Delta G° = -141.8 \frac{\textrm{kJ}}{\textrm{mol}}$.

Calculate $\Delta G$ at $25°C$ given $1.50 \textrm{ atm}$ $\textrm{SO}_2$, $1.00 \textrm{ atm}$ $\textrm{O}_2$, and $5.00 \textrm{ atm}$ $\textrm{SO}_3$.

A

$-82.9 \frac{\textrm{kJ}}{\textrm{mol}}$

B

$-135.8 \frac{\textrm{kJ}}{\textrm{mol}}$

C

$-138.8 \frac{\textrm{kJ}}{\textrm{mol}}$

D

$-141.3 \frac{\textrm{kJ}}{\textrm{mol}}$

E

$-141.7 \frac{\textrm{kJ}}{\textrm{mol}}$
