One mole of gas A at 300 K is mixed adiabatically with 5 moles of gas A at 400 K to produce 6 moles of gas A at 383.33 K. If $C_P^g/P_A = 7R/2$, calculate the entropy change. Select one: a. 0.1129 R b. 0.1192 R c. 0.9112 R d. 0.2119 R

Step 1
We know that the initial temperature of gas A is 300 K and the initial temperature of the mixture is 400 K. Since the mixture is adiabatic, there is no heat exchange with the surroundings, so the total energy of the system is conserved. This means that the final Show more…

An ideal gas at $300 \mathrm{K}$ is compressed isothermally to one-fifth its original volume. Determine the entropy change per mole of the gas.
Assuming that for CH4(g) CP – CV = R, find the entropy change resulting from heating 2 moles of the gas from 300 to 600 K at constant volume
