Calculate gibbs free energy formula

WebHowever, water's standard heat of formation for its liquid state is somewhere around -285.8 kJ/mol, which means you're going to have to put in that amount of energy to break those bonds. The thermal energy gotten from boiling water at 100 degrees is only 3.15 kJ/mol so you can see how high that temperature must be! 1 comment ( 84 votes) Upvote
