A) Endothermic and decreasing disorder
B) Exothermic and increasing disorder
C) Endothermic and increasing disorder
D) Exothermic and decreasing disorder
Correct Answer: B
Solution :
Entropy is the measurement of disordemess as disorderness increases entropy increases and if disordemess decreases entropy will decrease. For spontaneous reaction value of free energy change \[(\Delta G)\] is always negative. \[\Delta G=\Delta H-T\Delta S\] For always negative value of \[\Delta G,\] value of \[\Delta H\]should be negative and value of\[\Delta H\]should be positive, Negative value of \[\Delta H\] indicates exothermic reaction and positive value of \[\Delta H\] indicates increase in disordemess.
