Consider the reaction: CO(g) + Cl2(g)COCl2(g) Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.50 moles of CO(g) react at standard conditions. S°system = J/K

Acontrol during an experiment. might change remains constant does not exist does change

Consider the story you just read. all but one of the choices below indicate that something is living.
