the question is asking us What is this time that states standard states sustain it states Very small. A difference? Definitely. So we can ask any state point gas but the queen in us for substances. So you sure? Solid. So why you gas? We guess there stand estates, uh, used to feel gas at the pressure off exactly what not to spare. So the appeal gas pure gas. That's exactly at peace. Because to one atmosphere that B was wanting Thio. What liquid? Well, Sarid stunt at state. For liquid or solid, it's appear soft stance, and it's more stable form at the pressure of one that must bear on temperature. It's justified degree Celsius, PR liquid or solid. That's P waas one that most there on simply jaw. It cost 25 degrees cell issues and, well, uh ah, soft stance in solution, Miss solution. The standard States for that substance is the concentration hot, warm order. So the concentration off the substance That's one more than okay, So those are the definition of standard stage for the Saudis. Belief with gases by substances solution. Question is also asking us that watches standout and dopey change for your reaction. So I understand that hand topic. Change some dad until you change normally, depict Ernest, uh, doubt to Paige. Which do you know what? So the change in entropy appoint process when hall the reactant and product tiniest time the states. That is what it called this time. This is yes. Paige Changing answer p when all the reactions imprudence, huh? He India Standard States we just a standard states that will describe right here.
