Sodium carbonate can be made by heating sodium bicarbonate: 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) At 25°C, for this reaction,
insens350 [35]

Answer:

401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.

Explanation:

The expression for the standard change in free energy is:

\Delta G=\Delta H-T\times \Delta S

Where,  

\Delta G is the change in the Gibbs free energy.

T is the absolute temperature. (T in kelvins)

\Delta H is the enthalpy change of the reaction.

\Delta S is the change in entropy.

Given at:-

Temperature = 25.0 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (25.0 + 273.15) K = 298.15 K

\Delta H = 128.9 kJ/mol

\Delta G = 33.1 kJ/mol

Applying in the above equation, we get as:-

33.1=128.9-298.15\times \Delta S

-29815\Delta S=-9580

\Delta S=-9580 = 0.32131 kJ/Kmol

So, For reaction to be spontaneous, \Delta G

Thus, For minimum temperature:-

\Delta H-T\times \Delta S=0

128.9-T\times 0.32131=0

T=\frac{128.9}{0.32131}=401.17\ K

<u>Hence, 401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.</u>

Identify the neutralization reaction.
dusya [7]

The neutralization reaction among all the reactions would be the one between an acid and a base to produce salt and water.

<h3>What is a neutralization reaction?</h3>

It is a reaction involving an acid and a base to produce salt and water.

From the list of reactions, the only reaction that involves acid and a base with salt and water being the products is the first reaction.

Thus, the neutralization reaction is represented by the equation:

2H_3PO_4 + 3Ba(OH)_2 --- > 6H_2O + Ba(PO_4)_2

Name the following base: NaOH
soldier1979 [14.2K]

Answer:

Arrhenius Base

Explanation:

"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."
