In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. Which postulate of ki
ipn [44]

The kinetic energy of gas particles depends on temperature. Greater the temperature higher will be the average kinetic energy

Kinetic energy is related to the temperature as:

KE = 3/2 kT

where k = Boltzmann constant

T = temperature

In the given example, since the temperature of O2 gas is maintained at room temperature, the average KE will also remain constant.

The fifth postulate of the kinetic molecular theory which states that the temperature of the gas depends on the average KE of the particles of the gas explains the above observation.

As a chemical reaction proceeds toward equilibrium, the free energy of the system decreases at constant temperature and constant
olganol [36]

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>.
