NO 2 required for a reaction is produced by the decomposition of N 2 O 5 in CCl 4 as per the equation, 2N 2 O 5 (g) → 4NO 2 (g) + O 2 (g). The initial concentration of N 2 O 5 is 3.00 mol L –1 and it is 2.75 mol L –1 after 30 minutes. The rate of formation of NO 2 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 CAREER POINT CAREER POINT , CP Tower, IPIA, Road No.1, Kota (Raj.), : 0744-6630500 | www.ecareerpoint.com Email: info@cpil.in Page # 5 JEE Main Online
