Hi everyone,

I am having difficulty understanding this question. The explanation that Destroyer provides seems really basic. Could someone provide greater detail so I can thoroughly understand the concept.

Thank you

A very negative delta G means that a reaction will proceed spontaneously. Spontaneous rxns are thermodynamically favorable. When a rxn is very spontaneous, as indicated by the negative delta G, it will pretty much proceed to completion since it is so favorable (I.e, the products will make up nearly the entire equilibrium mixture). However, delta G does not tell us anything about the rxn rate, don't confuse those concepts. It tells us about thermodynamics, not kinetics

Thanks everyone for your answers.

yup. and choice A which talks about it being prduced fast, thats actually in the realm of kinetics. thermodynamics (the stuff dealing with spontaneity and delta G) and kinetics are different. you cant deduce kinetic info just from the thermo info. in the problem they only have u thermo info so only two answers as above poster mentioned above are correct.

i will admit the other answers look very enticing lol!
