Question

# State True or False.The dependence of electrode potential for the electrode $$M^{n+} / M$$ with concentration under STP condition is given by the expression:$$E = \displaystyle E^o + \frac{0.0591}{n} log_{10} [M^{n+}]$$

A
True
B
False

Solution

## The correct option is A TrueAccording to Nernst equation:$$E = E^o-0.0591logQ/n$$So for $$M^{n+} +ne \rightarrow M$$$$E = \displaystyle E^o - \frac{0.0591}{n} log_{10}M/[M^{n+}]$$$$E = \displaystyle E^o + \frac{0.0591}{n} log_{10} [M^{n+}]$$Chemistry
