At constant volume, 6.0 mol of H ₂ gas at 0^ C and 100 kPa was heated to 250 kPa . The molar heat of H ₂ at constant pressure ( C _ P )=28.9 ~J ~mol ⁻¹ . ( assume that the heat capacity values do not change with temperature). The final temperature of the H ₂ gas and the change in entropy of the process are
Options
- A273^0 C and 113 ~kJ ~mol ⁻¹ ~K ⁻¹
- B410^0 C and 158.8 ~J ~mol ⁻¹ ~K ⁻¹
- C682.5^0 C and 113 ~J ~mol ⁻¹ ~K ⁻¹
- D682.5 K and 113 ~J ~mol ⁻¹ ~K ⁻¹
Correct answer
D. 682.5 K and 113 ~J ~mol ⁻¹ ~K ⁻¹
