A PH Meter Uses an Electrode Arrangement That Provides a Voltage

A pH meter uses an electrode arrangement that provides a voltage that depends on [H⁺], in accord with the Nernst equation.The following plot illustrates this dependence.What effect would changing temperature have on the measurement and this plot?

A) A change of temperature would have no effect.
B) An increase in temperature would increase the slope.
C) An increase in temperature would decrease the slope.
D) An increase in temperature would increase the y intercept.
E) An increase in temperature would decrease the y intercept.
