Lavelle's review slides

Postby JosephineF » Thu Mar 12, 2020 7:51 am

In Lavelle's review there is a problem talking about calculating the Gibbs free energy under non equilibrium condition and in the end is positive. The slide says that because it is positive the reaction is spontaneous. I thought in order for a reaction to be spontaneous had to be negative. Is there some other symbol that im thinking of, where negativity= spontaneity?

He's referencing deltaG overall. He used this equation to see which side (reactants or products) will be favored given the conditions. Since deltaG is positive, it isn't spontaneous but that's for the forward reaction, the reverse reaction will be spontaneous in this case.
