QNEET-2023-Ch-272: NEET 2023 Chemistry - Class 11 NEET-2023-Ch-272 Solution: Consider the following reaction :- \(2H_2(g) + O_2(g) 2H_2O(g)…

Consider the following reaction :-

2H_2(g) + O_2(g) \rightleftharpoons 2H_2O(g) \Delta_r H = -483.64\ \text{kJ}

. What is the enthalpy change for decomposition of one mole of water? (Choose the right option). 120.9 kJ 241.82 kJ 18 kJ 100 kJ

Step-by-Step Verified Solution

Decomposition for 1 mole of water H 2 O ( g ) _ H 2 ( g ) + 1 2 O 2 ( g ) ; _ H = + 483.64 2 _ H = + 241.82 kJ
