One Mole of an Ideal Gas Is Compressed Isothermally at 607.4

One mole of an ideal gas is compressed isothermally at 607.4 K from 5.60 atm to 8.90 atm. If the process is carried out in two irreversible steps (intermediate step at P = 7.00 atm) , calculate the following. $\Delta$ S

A) 0 J/K
B) -3.85 J/K
C) 3.85 J/K
D) -2.34 J/K
E) 2.34 J/K
