Answer:
True
Explanation:
GIBBS FREE ENERGY (G) Gibbs free energy is a thermodynamic function It is a state function. G = H - TS At constant temperature At constant pressure and temperature An increase in S corresponds to a decrease in free energy
Constant free energy (G) P, T The important thing about free energy is that whenever the pressure and temperature are constant, we can determine the spontaneity of a process only in terms of the thermodynamic properties of the system G = H - TS The Free energy change is a measure of the change in the total entropy of a system and its environment at constant temperature and pressure. <u>Spontaneous processes at constant temperature and pressure are accompanied by a decrease in free energy</u>.
At constant temperature and pressure, the direction of spontaneous change is towards the lowest free energy. <u>The equilibrium state of a system corresponds to the lowest point of the free energy curve
</u>.
Answer:
The moon appears to change forms
Explanation:
As it rotates around Earth, sunlight only hits half of the moon which creates that impression
Answer:
1.2×10^7 dm³
Explanation:
1 mole of sulfur dioxide weighs 64 grams, so 64 tonnes is 10^6 moles.
The reaction of interest is ...
2SO₂ +O₂ ⇆ 2SO₃
This reaction uses half as many moles of oxygen as of sulfur dioxide. That is, 5×10^5 moles of oxygen are required. That quantity will have a volume of ...
(5×10^5 mol)(24 dm³/mol) = 1.2×10^7 dm³ . . . volume of oxygen needed
