Question

The enthalpy of the reaction $H subscript 2 left parenthesis g right parenthesis end subscript plus fraction numerator 1 over denominator 2 end fraction O subscript 2 left parenthesis g right parenthesis end subscript rightwards arrow H subscript 2 end subscript O subscript left parenthesis g right parenthesis end subscript$ is $increment$ H₁ and that of $H subscript 2 left parenthesis g right parenthesis end subscript plus fraction numerator 1 over denominator 2 end fraction O subscript 2 left parenthesis g right parenthesis end subscript rightwards arrow H subscript 2 end subscript O subscript left parenthesis l right parenthesis end subscript$ is $increment$ H₂ Then

${ΔH}_{1} < {ΔH}_{2}$
$Δ H_{1} + Δ H_{2} = 0$
$Δ H_{1} > Δ H_{2}$
$Δ H_{1} = Δ H_{2}$

The correct answer is: $ΔH subscript 1 less than ΔH subscript 2$
