Question

In previous problem calculate $\Delta s$gas if process is carried out at constant volume :

• A. 5R ln 2
• B. $\frac{3}{2}$R ln 2
• C. 3R ln 2
• D. –3R ln 2

Answer 1

Answer: (C)

3R ln 2

Answer 2

$\Delta$Sgas = nCv, m In $\frac{T_{2}}{T_{1}}$= 2 × $\left( \frac{5}{2} - 1 \right)$R In 2 = 3 R In 2
