Feb 23, 2007 I was reading through the chapter on equilibrium and it says that the Keq can change only if temperature changes - whereas changes in reactant/product concentration or pressure doesn't change Keq. I can't seem to figure out why temperature would change Keq. That equation is used to calculate the delta G given the equilibrium constant at. Mar 14, 2019 The cell potential and free energy example shows how to calculate free energy of a redox reaction. If ΔG = 0:, solve for E cell 0 = -nFE cell E cell = 0 V This means, at equilibrium, the potential of the cell is zero. The reaction progresses forward and backward at the same rate, meaning there is no net electron flow. With no electron flow, there is no current and the potential is equal to zero. Apr 27, 2010 I converted the C to K, but my answer came out wrong. Delta G is -5.2 kJ at 30 C Calculate Keq So, Keq = e^-(G/-RT I put Keq= e^-(.0052/(8.314)(303K) and I got 1.0 the correct answer i s 7.879 the last part of the question says 'Calculate Ksp at 30C but I.

Explanation:
The equilibrium constant of a reaction under the general form:
can be calculated by the general expression of #K_(eq)# as follows:
Therefore, #K_(eq)=([C][D])/([A][B])=K_c#
If the reactants and products are gases, we can also calculate the equilibrium constant using pressures, in this case the equilibrium constant is called #K_P# :
Note that, if any of the reactants or products are in the liquid or solid states, these are not included in the expression of the equilibrium constant.

For example, consider the following general reaction:

Thus, the equilibrium constant #K_c# expression is written as:

Note that aqueous state is treated as gases, however, we don't calculate #K_P# in this case from pressures, therefore, we only find #K_c# :
