The following reaction is carried out at 1 atm and 300 K 2H2(g) + O2(g) → 2H2O (l) ΔU
for the above reaction is 550 kJ. Assuming ideal gas behaviour for H2 and O2, calculate the value of ΔH. The value of gas constant, R = 0.082 L atm mol-1 K-1 = 8.314 mol-1 K-1.
[Given: The volume of 1 mole of liquid water is 18 mL under the above reaction condition]
