QUESTION 13 A sample containing 2.3 mol of ideal gas at pressure of 2 bar undergoes constant pressure heating form 250K to 400 K. If the constant volume heat capacity CV,m for this gas is 3/2R, and the surrounding temperature is 400K, calculate q, AH, AS, AS sur and AStotal for this process. Is this process spontaneous? Instruction: (1) The units of q and AH are in kJ (not J), and units of AS are J/K (2) Please do not use E notation. Please round all your answers to 2 decimal places, for example, -101.245 is written as -101.25. (1) q (kJ) = (2) ΔΗ (KJ) = (3) AS (J/K) = (4) ASsur (J/K) = (5) AStot (J/K) =

A sample containing 2.3 mol of ideal gas at pressure of 2 bar undergoes constant pressure heating form 250K to 400 K.
If the constant volume heat capacity CV,m for this gas is 3/2R, and the surrounding temperature is 400K, calculate q, AH,
AS, AS sur and AStotal for this process. Is this process spontaneous?
Instruction:
(1) The units of q and AH are in kJ (not J), and units of AS are J/K
(2) Please do not use E notation. Please round all your answers to 2 decimal places, for example, -101.245 is written as
-101.25.
(1) q (kJ) =
(2) ΔΗ (KJ) =
(3) AS (J/K) =
(4) ASsur (J/K) =
(5) AStot (J/K) =
