• # question_answer When two mole of an ideal gas $\left( Cp\,\,=\,\,\frac{5}{2}R \right)$ heated from 300 K to 600 K at constant pressure. The change in entropy of gas $\left( \Delta S \right)$ is- A) $\frac{3}{2}R\ell n2$                B) $-\frac{3}{2}R\ell n2$C) $5\,R\ell n2$                 D) $\frac{5}{2}\,R\ell n2$

$\Delta S\,=\,n{{C}_{p}}\ell n\frac{{{T}_{2}}}{{{T}_{1}}}$
