$\Delta G$ is an expression for the spontaneity of the reaction to occur, which we usually determine by observing if $\Delta G$ is positive or negative.
You know if $\Delta G$ should be positive or negative for the reaction to be spontaneous?

i believe that a negative sign indicates that it is spontaneous?

frostbite · Answer

That is correct. So if you had to answer your own question: Can water burn at 298 K if $\Delta G$ is positive?

lissiewalkin · Answer

so would it be as simple as saying...since it is spontaneous a reaction will occur therefore water does indeed burn at 298K?

frostbite · Answer

Remember that the free energy is positive, so not spontaneous, but yes... that is the general idea.

oh okay thanks for the help @Frostbite!

No problem at all.
