To calculate a milliequivalent (mEq) you have to have two pieces of information: The mass of the substance in question and the molar mass (or molecular weight) of that substance. You must also be able to identify its valence from its molecular formula, as this determines ion number in solution. How to calculate K, and how to use K to determine if a reaction strongly favors products or reactants at equilibrium. Reversible reactions, equilibrium, and the equilibrium constant K.

where:
#Q# is the reaction quotient for the current state of the reaction.#R# and#T# are known from the ideal gas law.#RTlnQ# describes the shift in the free energy in reference to standard pressure and the chosen temperature (usually#25^@ 'C'# for convenience).
At chemical equilibrium, the reaction has no tendency to shift in either direction, so the change in Gibbs' free energy is zero, i.e.
The revenant full movie online 2015 free. #DeltaG = 0#
Thus, with #Q = K# as well at equilibrium,

where #'exp'(x) = e^x# .

I'm thinking the fact that it's at equilibrium is what I'm not accounting for, but here is what I've done.
For Ecell I have F2 as my cathode and I as my anode.
