Answer:

The correct answer is option B.

Explanation:

Enthalpy of the system = \Delta H=+25 kJ=25,000 J

Entropy of the system =\Delta S=+5.0 J/K

Temperature of the system =T =23°C = 296 K

The Gibbs's free energy is given by;

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

\Delta G=25,000 J-296 K\times 5.0 J/K =23,520 J=23.5 kJ

The value of ΔG is positive which means that system is not spontaneous.

Hence, from the given options the most closest value to our answer is option B.

Explain how the concentration of hydronium ions and hydroxide ions are related to pH.
Dominik [7]
Hello!

The concentration of hydronium ions is related to pH by the following simple equation:

pH=-log[H_3O^{+}]

From this equation, you can see that as the hydronium concentration is higher, the pH will be lower.

The concentration of the OH⁻ ions is related to the pH by the following set of equations

pOH=-log[OH^{-}] \\ pH=14-pOH

You can see that as the concentration of OH⁻ is higher, the pOH is lower and thus the pH is higher. 

When the pH of the solution is less than 7, the solution is acidic.

When the pH of the solution is higher than 7, the solution is basic.

Have a nice day!
