A sample of argon gas at l-atm pressure and 27^@Cexpands reversibly andadiabatically from 1.25 dm^3to 2.50 dm^3 . Calculate the enthalpy change in this process. C_(v,m)for argon is 12.48 JK^(-1) "mol"^(-1) |

Answer» SOLUTION :T_1 = 300 K, cal `T_2 ` USING `T_2/T_1= (V_1/V_2)^(R//C_V)` `DELTA H = nC_p (T_2 - T_1) = n (C_v + R) (T_2 - T_1) ` -117.6 J |
