write the keq expression for the following reaction and determine the value of the Keq at 25degree celcius: MnO2(s)+4H+(aq)<-->Mn2+(aq)+2H2O(l)+Cl2(g)

Keq = (Mn^2+)*pCl2/(H+)^4

Use nFEocell= RTlnK.
Remember T must be in kelvin. Use 8.314 for R and use 96,485 for F. Note the correct spelling of celsius.
