Calculate the entropy change accompanying the following change of state
`5 mol` of `O_(2) (27^(@)C, 1 atm) rarr 5 mol of O_(2) (117^(@)C, 5 atm)`
`C_(P)` for `O_(2) = 5.95 cal deg^(-1) mol^(-1)`

Explanation

To calculate the entropy change (\( \Delta S \)) accompanying the change of state of \( 5 \, \text{mol} \) of \( O_2 \) from \( 27^\circ C \) (1 atm) to \( 117^\circ C \) (5 atm), we can use the formula:

\[ \Delta S = n C_p \ln\left(\frac{T_2}{T_1}\right) + n R \ln\left(\frac{P_1}{P_2}\right) \]

### Step 1: Convert temperatures to Kelvin
- Given \( T_1 = 27^\circ C \)
