NO2 required for a reaction is produced by the decomposition of N2O5 in CCl4 as per the equation,
2N2O5(g) → 4NO2(g) + O2(g)
The initial concentration of N2O5 is 3.00 mol L–1 and it is 2.75 mol L–1 after 30 minutes. The rate of formation of NO2 is :
(1) 2.083 × 10–3 mol L–1 min–1
(2) 8.333 × 10–3 mol L–1 min–1
(3) 4.167 × 10–3 mol L–1 min–1
(4) 1.667 × 10–2 mol L–1 min–1
