Assuming, R=8.3 ~J ~mol ⁻¹ ~K ⁻¹ and =1.4 the values of C_ p and C_ V of a gas are
Options
- A29.05 ~J ~mol ⁻¹ ~K ⁻¹, 20.75 ~J ~mol ⁻¹ ~K ⁻¹
- B20.75 ~J ~mol ⁻¹ ~K ⁻¹, 29.05 ~J ~mol ⁻¹ ~K ⁻¹
- C16.60 ~J ~mol ⁻¹ ~K ⁻¹, 8.300 ~J ~mol ⁻¹ ~K ⁻¹
- D8.300 ~J ~mol ⁻¹ ~K ⁻¹, 16.60 ~J ~mol ⁻¹ ~K ⁻¹
Correct answer
A. 29.05 ~J ~mol ⁻¹ ~K ⁻¹, 20.75 ~J ~mol ⁻¹ ~K ⁻¹
Step-by-step solution
Given, =1.4= C_ p C_ V C_ p =1.4 C_ V Also, R=C_ p -C_ V =8.3 (given) 1.4 C_ V -C_ V =8.3 or C_ V = 8.3 0.4 =20.75 Jmol ⁻¹ ~K ⁻¹C_ p =1.4 C_ V =1.4 20.75=29.05 Jmol ⁻¹ ~K ⁻¹
