<span>The
list of phases of H2O that is arranged in order of increasing entropy is from
solid then liquid then gas. Gaseous water has the most entropy because of the
random movement of water molecules. And Solid having the least entropy because the
water molecules are arranged in a specific order.</span>
Answer:
(D) Neither I nor II
Explanation:
The reagent potassium hydrogen phthalate is found in pure form and it is not partially hydrated .
The pallet form of NaOH ( solid form ) absorbs carbon dioxide gas from the atmosphere but NaOH in solution form does not absorb carbon dioxide .
Hence option D ) is right choice .
The standard enthalpy of formation (Δ
) is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements.
Standard enthalpies (Δ
) of formation for given reaction is 978.3 kJ
<h3>
What is Standard enthalpies of formation?</h3>
The standard enthalpy of formation is defined as the enthalpy change when one mole of a substance in the standard state (1 atm of pressure and 298.15 K) is formed from its pure elements under the same conditions.
Given reaction ;

To Find : Δ
Δ
= ∑np Δ
(products) – ∑np Δ
(reactants)
Δ
= [1(Δ
) + 4(Δ
)] – [1(Δ
) + 4(Δ
)]
Δ
= [1(0) + 4(-241.8)] – [1(+9.16) + 4(0)]
Δ
= [4(-241.8)] – [1(+9.16)] = 978.3 kJ
