What is the equilibrium expression for this reaction?
Answers
Answer:
B
Explanation:
The equilibrium expression is
[products]/[reactants] and each is raised to its molar coefficient.
So:
[H2}^2[O2]/[H2O]^2

pH value is the power of the hydrogen ions concentration in a solution. The more is the concertation more basic will be the solution, Less is the concertation more will be an acidic solution.
- The highest concertation of ions is 1.0 as the lower is pH level the higher is the concentration of ions. Hence the option B 1.0 has an aqueous solution that has more ions.
Learn more about the pH values indicating the highest concentration.
As H+ ions in solution exist as H3O+ ions, the lower the pH, the higher the concentration of H30+
