A(g) → 2B(g) + C(g) is a first order reaction. The initial pressure of the system was found to be 80 — JEE Mains Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

A(g)  2B(g) + C(g) t = 0 – – t = (10 min) 800 – P 2P P PT = 800 – P + 2P + P = 800 + 2P = 1600 So P = 400 mm So 1 t = 10 min Given time 30 min | JEE(Main) 2023 | DATE : 13-04-2023 (SHIFT-2) | PAPER-1 | CHEMISTRY PAGE # 8 So for Ist order Reaction Ct = n ) ( C n = 10 2   t t ; n = number of half life Ct = 3) ( 800 = 100 mm of Hg So after 30 min P = 700 mm PA = 800 – 700 = 100, PB = 1400, PC = 700 PT of reaction mixture = 100 + 1400 + 700 = 2200 mm of Hg
