∵ All reactants and products are liquid, hence, Δ ng=0 where, Δ n g signifies change in moles of gaseous substances. ∴ Δ H =Δ U +Δ n g RT or, Δ H =Δ U

Q. In a reaction, all reactant and products are liquid, then

$Δ H > Δ E$

$Δ H < Δ E$

$Δ H = Δ E$

Can't predicted

$∵$ All reactants and products are liquid,
hence, $Δ n_{g} = 0$
where, $Δ n_{g}$ signifies change in moles of gaseous substances.
$∴ Δ H = Δ U + Δ n_{g} RT$
or, $Δ H = Δ U$

Q. In a reaction, all reactant and products are liquid, then

ΔH>ΔE

ΔH<ΔE

ΔH=ΔE

Can't predicted

∵ All reactants and products are liquid, hence, Δng​=0 where, Δng​ signifies change in moles of gaseous substances. ∴ΔH=ΔU+Δng​RT or, ΔH=ΔU

$Δ H > Δ E$

$Δ H < Δ E$

$Δ H = Δ E$

$∵$ All reactants and products are liquid,
hence, $Δ n_{g} = 0$
where, $Δ n_{g}$ signifies change in moles of gaseous substances.
$∴ Δ H = Δ U + Δ n_{g} RT$
or, $Δ H = Δ U$
