    Yes,there are instances where the activation energy can be negative. There are reactions where the rate of the reaction decreases with increasing temperatures.So when you fit the rate constant into an arrhenius expression, it results in a negative activation energy.

    Nernst equation dekhlo Definition : Equation relating the voltage of a chemical cell to its standard cell potential and to the concentrations of the reactants and product. The Nernst equation is Ecell = E0cell - (RT/nF) x log10Q . where, Ecell is the cell potential.

    1Thank You

    Prashant Kumar 6 years, 10 months ago

    the Nernst equation is an equation that relates the reduction potential of an electrochemical reaction (half-cell or full cell reaction) to the standard electrode potential, temperature, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation.
