Jan 26, 2019 Equilibrium Constant Definition. The equilibrium constant is the value of the reaction quotient that is calculated from the expression for chemical equilibrium.It depends on the ionic strength and temperature and is independent of the concentrations of reactants and products in a solution. Basic definitions and properties. For a system undergoing a reversible reaction described by the general chemical equation + + ⋯ ⇌ + + ⋯ a thermodynamic equilibrium constant, denoted by ⊖, is defined to be the value of the reaction quotient Q t when forward and reverse reactions occur at the same rate. If the E o value is +ve then Keq 1 and a reaction with an E o value that is -ve will have a Keq Calculate the Keq value for the reaction between silver nitrate and metallic zinc: Is the reaction essentially complete or incomplete. Write the overall reaction: 2 AgNO 3 + Zn o - Zn(NO 3) 2 + 2 Ag o.
Calculate the value of Keqat 25.C
- Equilibrium Constant Calculator is a free online tool that displays the equilibrium constant for the given chemical reaction. BYJU’S online equilibrium constant calculator tool makes the calculation faster, and it displays the result in a fraction of seconds.
- Let’s now examine how to calculate equlibrium concentrations of cyclohexane conformers. Before beginning it must be clear that the A values (in Kcal!) are related to the equlibrium constant in the following manner: A =-DG x o = RT lnK eq; and Keq is is the equlibrium constant of a group going from axial to equitorial (a favored shift).
F2(g) + 2I- 2F-(aq) + I2(g)
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.
I got 2.331 for this.

Next I got my G value. G= -nFE -(2)(9.65x 104)(2.331)
I got -449,883 J for this.(I left it in joules for the next part)
I got -449,883 J for this.(I left it in joules for the next part)
How To Calculate Keq From Pka Values
Finally, I used the rearranged equation for the relation between G and K.
How To Calculate Keq From Delta G
Keq= ex of -(G/RT) -(-449,883/8.314 x 298)=181.58
