    Can Methane and Citric Acid be Balanced in a Redox Reaction?

    I meant the citric acid carbon, but clearly I've miscalculated. Consequently, both half reactions are actually oxidation reactions and the overall reaction is nonsensical.

    Can Methane and Citric Acid be Balanced in a Redox Reaction?

    Hi there: I'm trying to balance a reaction in which methane is oxidized by citric acid in solution. Both methane and citric acid will be transformed into carbon dioxide. To begin, I checked that the reaction is indeed a redox reaction. C6H8O7→CO2 So, I calculated the oxidation number for...

    Gibbs Free Energy of Formation: 1°C or 25°C? (And other exciting questions.)

    Aha! Makes sense. Thanks for explaining that.

    Gibbs Free Energy of Formation: 1°C or 25°C? (And other exciting questions.)

    Thanks for your reply DrDru, but I'm afraid I don't really follow. Perhaps a concrete example would help me understand. For example, consider this reaction at 50ºC (i.e., 323.15K): [A]+[B]→[C]+[D] Using ΔG=ΔG°+RT ln Q, I get something like this: ΔG=ΔG°+R×323.15×ln (([C][D])/([A][B]))...

    Gibbs Free Energy of Formation: 1°C or 25°C? (And other exciting questions.)

    Hi there: When using ΔG=ΔG°+RT ln Q to calculate the energy yield of a reaction, does it matter if I use ΔG° calculated at 1°C or 25°C? Also, why are there two choices and when are they each applicable? Finally, I have also seen ΔG°' written (note the prime). What does this mean and how does...
