Multiple choice thermodynamic question
« on: April 11, 2021, 02:24:34 AM »
 In which of the following processes, the process is always non-feasible?

a)ΔH > 0,ΔS > 0
b)ΔH < 0,ΔS > 0
c)ΔH > 0,ΔS < 0
d)ΔH < 0,ΔS < 0

 What is the meaning of O here? Does it mean Oxidation?

The process is always non-feasible at ΔH > 0, ΔS < 0. So the answer is C.
