Question

During a certain reversible process, the surroundings undergo an entropy change, ΔSsurr = - 71 J/K .

What is the entropy change of the system for this process?
ΔSsys =_____ J/K

Answer 1

entropy change of the system = +71 J/K

Step-by-step explanation:

for a reversible process ;

ΔSsurrounding + ΔSsystem = 0 ............(1)

but ΔSsurrounding = - 71 J/K

substitute in equation (1)

ΔSsystem = -ΔSsurrounding

ΔSsystem = -(- 71 J/K)

= +71 J/K
