Document Summary
Occur anytime 2 or more atoms,ions, or molecules collide in such a way that they produce a new substance. 1st law- energy can neither be created nor destroyed only converted from one form to another. 2nd law- when converting energy from one form to another the amount of useful energy decreases. Energy that is free and available to do work. The amount of energy when/for reactions to occur. G= h- t s delta- stands for change g- free energy h- enthalpy (heat energy) t- temperature (k) s- entropy (a measure of disorder more disorder, more entropy) Living vs. nonliving systems non- living less organized lower energy very slow living highly organized high energy fast (takes energy to get highly organized and get high energy comes from the sun) (fastness is due to the presence of enzymes) Enzyme function organic catalysts- speed up the rate of a reaction, but are not used up during the reaction.
