Question

Given that $\Delta G=\Delta H-T\Delta S$, how is the spontaneity of an endothermic reaction to change with decreasing $T$?

• A. Becomes less spontaneous
• B. Becomes more spontaneous
• C. Does not change
• D. Insufficient information to make a conclusion
  

Answer 1

The correct option is D Insufficient information to make a conclusion

$\text{Since the energy of the system decreases during an exothermic reaction.}$

$\text{The products of the system are more stable}$ $\text{than the reactants.}$

$\text{However,endothermic reaction do occur spontaneously.}$

$\Delta G=\Delta H-T\Delta S$ $\text{We should also have the value of enthalpy change so that to check spontaneity.}$
