The second law of thermodynamics is a fundamental law of science. In this problem, we consider the thermodynamics of an ideal gas, phase transition, and chemical equilibrium.
Three moles of `CO_(2)` gas expands isothermally (in thermal contact with the surroundings, temperature `= 15.0^(@)C`) against a fixed external pressure of `1.00 bar`. The initial and final volumes of the gas are `10.0 L` and `30.0L`, respectively.
Select the correct order of the entropy change.

Options

A. `Delta_(sys)S gt 0, Delta_(surr)S = 0`
B. `Delta_(sys)S lt 0, Delta_(surr)S gt 0`
C. `Delta_(sys)S gt 0, Delta_(surr)S lt 0`
D. `Delta_(sys)S gt 0, Delta_(surr)S = 0`

Explanation

In expansion of `CO_(2)` gas molecule, entropy of system `Delta_(sys)S` increases or `Delta_(sys)S gt 0` and entropy of surrounding decreases `Delta_(surr)S lt 0`.
