Explanation:
It is known that relation between entropy, heat energy and temperature is as follows.
dS =
Also we know that at constant pressure, Q =
As the given data is as follows.
= 298 K,
= 348 K
= 29.355 J/K mol
Now, putting the given values into the above formula as follows.
=
=
= 4.48 J/k mol
Thus, we can conclude that the increase in the molar entropy of given oxygen gas is 4.48 J/k mol.
