Determine the equilibrium constant at 255 K for the following reaction under acidic conditions 4H+(aq) + MnO, (s) +2Fe2+ (aq)-> Mn2+ (aq) +2Fe3+ (aq) + 2H,0? The two half-reactions are: MnO2(s) +4H+(aq) + 2e-? Mn2+(aq) + 2H20(1) E?-1.23 V Fe3-(aq) + e-? Fe2 + (ag) E -0.770 V

A dynamic chemical system approaches chemical equilibrium when enough time has passed and its composition no longer exhibits any discernible tendency to change further. The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium.
The equilibrium constant for a specific set of reaction conditions is unaffected by the initial analytical concentrations of the reactant and product species in the mixture.
As a result, it is possible to calculate the composition of a system at equilibrium using known equilibrium constant values and the initial composition of the system. The value of the equilibrium constant, however, could be affected by reaction variables including temperature, solvent, and ionic strength.
For the comprehension of many chemical systems, equilibrium constant knowledge is crucial.
