The nature of curve of `E_(cell)^(@)` vs. log `K_c` is :

The nature of curve of E^(@) cell against log K_(C ) is:

Plot the curve y=log_(e)(-x)

Equilibrium constant K is related to E_("cell")^(@) and not E_("cell") because

The ratio of slopes of K_(max) vs. V and V_(0) vs. v curves in the photoelectric effect gives (v= freqency. K_(max) = maximum kinetic energy, V_(0) =stopping potential) :

A graph is plotted between E_(cell) and log .([Zn^(2+)])/([Cu^(2+)]) . The curve is linear with intercept on E_(cell) axis equals to 1.10V . Calculate E_(cell) for the cell. Zn(s)||Zn^(2+)(0.1M)||Cu^(2+)(0.01M)|Cu

You are given the following cell at 298 K with E_(cell)^(@)=1.10V Zn(s)|Zn^(2+)(C_(1))||Cu^(++)(C_(2))|Cu(s) where C_(1) and C_(2) are the concentration in mol/lit then which of the following figures correctly correlates E_(cell) as a function of concentrations x-axis log((C_(1))/(C_(2))) and y-axis E_(cell)
