A) Exothermic if \[A>0\]and \[B<0\]
B) Endothermic if \[A<0\] and \[B>0\]
C) Endothermic if \[A>0\]
D) Exothermic if \[B<0\]
Correct Answer: C
Solution :
\[\Delta {{G}^{o}}=\Delta {{H}^{o}}-T\Delta {{S}^{o}}\] Given that A and B are non-zero constants, i.e., \[A=\Delta {{H}^{o}},B=\Delta {{S}^{o}}\]if \[\Delta {{H}^{o}}\]is positive means reaction is endothermic.
