Question
ᐃSsurr for an exothermic reaction is
Options
A.always positive
B.always negative
C.zero
D.may be positive or negative
Solution
Heat is released in an exothermic process which increases the entropy ofsurroundings.When entropy of the system is positive, overall entropy change is alsopositive. In some exothermic reaction, entropy of system may decrease.
