\( \mathrm{NO}_{2} \) required for a reaction is produced by the decomposition of \( \mathrm{N}_{2} \mathrm{O}_{5} \) in \( \mathrm{CCl}_{4} \) as per the
\( \mathrm{P} \)
equation, \( 2 \mathrm{~N}_{2} \mathrm{O}_{5}(\mathrm{~g}) \rightarrow 4 \mathrm{NO}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \)
W
The initial concentration of \( \mathrm{N}_{2} \mathrm{O}_{5} \) is \( 3.00 \mathrm{~mol} / \mathrm{L} \) and it is \( 2.75 \mathrm{~mol} / \mathrm{L} \) after 30 minutes. The rate of formation of \( \mathrm{NO}_{2} \) is
(1) \( 4.167 \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~min}^{-1} \)
(2) \( 1.667 \times 10^{-2} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~min}^{-1} \)
(3) \( 8.333 \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~min}^{-1} \)
(4) \( 2.083 \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~min}^{-1} \)
