One mole of an ideal gas at T1 = 300.0 K, p1 = 2.4618 atm, and V1 = 10.00 L is isother- mally expanded to V2 = 20.00 L against a constant external pressure of 1.2309 atm. Calculate ∆U, ∆H, q, w, and ∆S. Compare your results for ∆S and q/T and explain whether your results are consistent with the second law of Thermodynamics.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
