Cell Thermodynamics and Temperature

The negative standard entropy change reflects the loss of gaseous hydrogen in the cell reaction. Finally, 

Consider the cell shown in Problem 1.12. How much heat is absorbed by the cell if it discharges iso thermally and reversibly How much heat (q) is absorbed if it discharges at constant external pressure, doing only reversible pV work (that is, no electrical work)  

If the cell operates doing no work but with constant external pressure, then 

For the reduction of CIOJ to CIOJ the standard electrode potential under alkaline conditions is +0.37 V, while under acidic conditions it is+1.20 V. Write a balanced half-cell reaction for each reduction and deduce the value for the ionic product of water, JCw. 

Calculate the equilibrium constant for the disproportionation (fCjisp) of MnOOH to Mn + and MnOa at pH 3, given
