I Review Constants Periodic Table
For a certain chemical reaction, AH° = -35.8 kJ and AS° = -80.0 J/K.
Part A
Is the reaction exothermic or endothermic?
O exothermic
O endothermic
Submit
Prevlous Anewere
v Correct
Anegative enthalpy value indicates that energy is released by the system. Therefore, the reaction is exothemic.
Part B
Does the reaction lead to an increase or decrease in the disorder of the system?
O increase
O decrease
Submit
Previous Anawere
v Correct
The sign of the entropy change is negative, which indicates that the disorder, or entropy, of the system has decreased.
