Question
Water decomposes at 2300 K H2O(g) H2 (g) + 2 1 O2(g) The percent of water decomposing at 2300 K and 1 bar is ____________ (Nearest integer). Equilibrium constant for the reactions is 2 × 10–3 at 2300 K.
Answer: .
💡 Solution & Explanation
H2O(g) ⇌ H2(g) + 1 O2(g) 1– /2 Kp = – 2 . 1 = 2 × 10–3 = ) – ( 2 = 2 × 10–3 = 2 = 2 2 × 10–3 ( << 1) 2 = 8 × 10–3 ()3 = (2)3 × 10–6 = 2 × 10–2 % = 2 × 10–2 × 100 = 2 | JEE(Main) 2023 | DATE : 29-01-2023 (SHIFT-1) | PAPER-1 | OFFICIAL PAPER | CHEMISTRY PAGE # 9
