Question

are these right? 

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) 14.34
(2) AH (KJ) = 14.34
(3) AS (J/K) = 44.94
(4) ASsur (J/K) = -35.84
(5) AStot (J/K) = -9.08
Continue with the last question. Base on your calculation, what is the spontaneity of this process?
O This process is not spontaneous becasue ASsur <0
This process is spontaneous because AStotal >0
O This process is in equilibrium
O we do not have enough information to tell about the spontaneity
