6.7639104*10^0 is the answer.
Answer:
Molarity = 0.21 M
Explanation:
Moles <em>solute </em>(mol) = Volume <em>solution</em> (L) x Molarity <em>solution </em>(M)
0.56 mol NaCl = 2.7 L x M
M = 0.2074074074
Given the pH of the solution, we can determine [H⁺].
pH = -log[H⁺]
[H⁺] = 10⁻⁷·⁷⁸
[H⁺] = 1.659586907 x 10⁻⁸ M
We also know that pOH = 14 - pH. Thus, the pOH is 6.22. Given the pOH of the solution, we can determine [OH⁻].
pOH = -log[OH⁻]
[OH⁻] = 10⁻6.22
[OH⁻] = 6.02559586 x 10⁻⁷ M
The ionic product of water Kw, can then be calculated using the following equation.
Kw = [H⁺][OH⁻]
Kw = (1.659586907 x 10⁻⁸)(6.02559586 x 10⁻⁷)
Kw = 1.0 x 10⁻¹⁴
Answer:
The value of Gibbs free energy of the reaction is negative which means that reaction is spontaneous.
Explanation:
ΔG° = ΔH° - TΔG°
Where:
ΔG° = Change in Gibbs free energy at T temperature
ΔH° = Enthalpy of reaction at T temperature
ΔS° = Entropy change of reaction at T temperature
- The reaction with negative value of Gibbs free energy are spontaneous.
- The reaction with positive value of Gibbs free energy are non spontaneous.
A → B ,ΔG° = -40
The value of Gibbs free energy of the reaction is negative which means that reaction is spontaneous.
