Oxygen is heated from 300 to 600 at a constant pressure of 1 bar. What is the increase in molar entropy ? The molar heat capacity in `JK^(-1)mol^(-1)` for the `O_(2)` is
`C_(P)=25.5+13.6xx10^(-3)T-42.5xx10^(-7)T^(2)`

Explanation

To find the increase in molar entropy (\( \Delta S \)) of oxygen when it is heated from 300 K to 600 K at a constant pressure of 1 bar, we can use the formula:

\[ \Delta S = n \int_{T_1}^{T_2} \frac{C_P}{T} dT \]

where:
- \( n \) is the number of moles (which is 1 for this case),
