Answer to Question #218305 in Civil and Environmental Engineering for syra

Question

A voltaic cell is constructed that uses the following reaction and operates at 298K:
Zn(s) + Ni

Answer 1

$E_{cell}=E_{cell}^0=-\frac{RT}{nF}\ln\frac{P}{R}\\ E_{cell}=E_{cell}^0=-\frac{0.0591}{2}\ln\frac{0.137}{3.94}=0.55 V$
