Problem

Consider the cell Pt(s)|

H_2

(g,

1.0\,\text{atm}

H^{+}

(1.0 M) ||

Cl_2

(g,

1.0\,\text{atm}

Cl^{-}

(1.0 M)|Pt(s). Predict the qualitative effect on the cell potential if the pressure of

H_2

is lowered to

0.20\,\text{atm}

while all other conditions remain unchanged. Indicate whether

E

increases, decreases, or stays the same and support your answer briefly.
