endergonic

a chemical reaction that has a positive G is correctly describes as

25/1000= .025-- 298*.25---= -897.45

assume that temperature is 298 K, calculate G, when H is -890 kJ/mol and S is 25 J/K

G is the change in free energy

the mathematical expression for the change in free energy of a system is delta G=H-T*S. Which of the following is (are) correct?

it is lost to the environment

when chemical, transport, or mechanical work is done by an organism, what happens to the heat generated

entropy of the universe

whenever energy is transformed, there is always an increase in the
