Question

For a reaction $\Delta H=9.08kJmo{l}^{-1}$ and $\Delta S=35.7J{K}^{-1}mo{l}^{-1}$. Which of the following statements is correct for the reaction

• A. Reversible and Isothermal
• B. Reversible and Exothermic
• C. Spontaneous and Endothermic
• D. Spontaneous and Exothermic

Answer 1

The correct option is C

Spontaneous and Endothermic

$\Delta H$ and $\Delta S$ both are +ve for spontaneous change, and $\Delta H=+ve$ for endothermic reaction.
