At constant volume, 6.0 mol of

\mathrm{H}_2

gas at

0^{{}^{{}^{\circ}}} \mathrm{C}

and 100 kPa was heated to 250 kPa . The molar heat of

\mathrm{H}_2

at constant pressure \left(\mathrm{C}_{\mathrm{P}}\right)=28.9 \mathrm{~J} \mathrm{~mol}^{-1}

. ( assume that the heat capacity values do not change with temperature). The final temperature of the

\mathrm{H}_2

gas and the change in entropy of the process are

A $273^0 \mathrm{C}$ and $113 \mathrm{~kJ} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$
B $410^0 \mathrm{C}$ and $158.8 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$
C $682.5^0 \mathrm{C}$ and $113 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$
D682.5 K and $113 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$

D. 682.5 K and $113 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$
