Breaking bonds endothermic
WebThis is a phenomenal answer!! 2. crossed-aldol • 3 yr. ago. Forming a bond is always exergonic. Breaking a bond is always endergonic. But let’s say it takes 10 joules of energy to break a bond and then you form a bond which releases 20 joules, then the overall process ends up so being exergonic because you have a net yield of 10 joules.
