Zn²⁺ + Mn Mn²⁺ + Zn

Given [Mn²⁺] = 0.200 M

[ Zn²⁺] = 0.100 M

E^o = 0.42 V

We know that

$E=E^{o}-\frac{0.059}{n}log\frac{\left [ Mn^{2+}]}{\left [ Zn^{2+}]}$

Where

n = number of electrons transferred = 2

PLug the values we get

cell potential , E = 0.411 V

A gaseous mixture of 25% CO, 25% CO2, 25% H2 and 25% H20 is brought to a temperature T and 1atm. Equilbirium composition of the gas mixture is determined by the following reaction CO2 + H2 = CO + H20. Calulate the equilbirium composition of the gaseous phase at 700K and at 1500K. Given G at 700K is 14kJ and at 1500K is -9.6kJ
