A) \[{{C}_{v}}\ln \,2\]
B) \[{{C}_{p}}\,ln\text{ }2\]
C) \[R\text{ }ln\,2\]
D) \[\left( {{C}_{v}}-R \right)\text{ }ln\text{ }2\]
Correct Answer: D
Solution :
\[\Delta S\,\,=\,\,n{{C}_{v}}\,In\,\,\frac{{{T}_{2}}}{{{T}_{1}}}\,\,+\,\,nR\,\,\,In\,\,\frac{{{V}_{2}}}{{{V}_{1}}}\] \[\Delta S\,\,=\,\,{{C}_{v}}\,In\,2-R\,\,In\,\,2\] \[\Delta S=\left( {{C}_{V}}-R \right)\text{ }In\text{ }2\]You need to login to perform this action.
