## Homework Statement

The reduction of O

_{2}to H

_{2}O in acidic solution has a standard reduction potential of +1.23 V. What is the effect on the half-cell potential at 25 °C when the pH of the solution is increased by one unit?

O

_{2}

_{(g)}+ 4H

^{+}

_{(aq)}+ 4e

^{-}–> 2 H

_{2}O(l)

(A) The half-cell potential decreases by 59 mV.

(B) The half-cell potential increases by 59 mV.

(C) The half-cell potential decreases by 236 mV.

(D) The half-cell potential increases by 236 mV.

Nernst Equation

## The Attempt at a Solution

I'm aware this is a Nernst equation problem. Yet, I'm not exactly sure how to apply it. It appears to me that the reaction quotient would be 0, since there is only a pure liquid on the product side. As such, I am not sure how to approach the problem.
