± Gibbs Free Energy: Temperature Dependence Gibbs free energy (G) is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, and is minimized at equilibrium. It is defined as G=H−TS where H is enthalpy, T is temperature, and S is entropy. The chemical reaction that causes aluminum to corrode in air is given by 4Al+3O2→2Al2O3 in which at 298 K ΔH∘rxn = −3352 kJ ΔS∘rxn = −625.1 J/K Part A What is...

So I had to calculate the Gibbs Free energy for all the reactions: Ca(s)+CO2(g)+12O2(g)→CaCO3(s) = ΔG∘ = -734  kJ   CaCO3(s)→CaO(s)+CO2(g) = 131  kJ CO(g)+H2O(g)→H2(g)+CO2(g) = -28.6 KJ but now I have to predict what lowering the temeprature will do to Gibbs Free Energy: it will decrease with decreasing temp. ΔG∘ will increase with decreasing temperature. ΔG∘ will change slightly with decreasing temperature.

Assume we know the Gibbs free energy of reaction for a chemical reaction taking place at 298 K. What additional thermodynamic information do we need to know to compute the equilibrium constant of the reaction (a) at 298 K and (b) at 350 K? (You may assume that no phase transitions take place in this temperature range.)

So my professor is asking us for the electric potential energy formula and the electric kinetic energy formula. He gives us two equations and asks if each equation is correct. I pretty sure that the potential energy one is correct, but I can't find the Kinetic energy equation. PE=(Ke*(q1*q2))/r KE=(Ke*(q1*q2))/r^2 Are these equations correct? If not, what are the correct equations?
