Question

Calculate the work done in the oxidation of one mole $HCl_{(g)}$ at 27$^\circ$C, according to reaction.
$4HCl_{(g)} + O_{2(g)} \rightarrow 2Cl_{2(g)} + 2H_2O_{(g)}$
(R = 8.314 J K$^{-1}$ mol$^{-1}$)

• A. 2494.2 J
• B. 623.6 J
• C. 1247.1 J
• D. 1870.7 J

Hint:

Work is done on the system when $\Delta n_g$ is negative (compression).

Answer 1

The Correct Option is B
