Calculate S (for the system) when the state of 3.10 mol of perfect gas atoms, for which C p ,m = 5/2 R ,

Calculate Δ S (for the system) when the state of 3.10 mol of perfect gas atoms, for which C _{p ,m} = 5/2 R , is changed from 25°C and 1.00 atm to 125°C and 5.00 atm.

How do you rationalize the sign of Δ S ?

a. Though Δ S (system) is positive, the process can still occur spontaneously if Δ S (total) is negative.

b. Though Δ S (total) is negative, the process can still occur spontaneously if Δ S (system) is positive.

c. Though Δ S (system) is negative, the process can not occur spontaneously if Δ S (total) is positive.

d. Though Δ S (system) is negative, the process can still occur spontaneously if Δ S (total) is positive.
