Q. For a reaction, $\mathrm{\Delta}H = 9.08\ kJ\ mol^{- 1}$and $\mathrm{\Delta}S = 35.7\ JK^{- 1}mol^{- 1}$. Which of the following statement is correct for the reaction?
A) Reversible and isothermal
B) Reversible and exothermic
C) Spontaneous and endothermic
D) Spontaneous and exothermic
Explanation
(c)
$\mathrm{\Delta}H$ and $\mathrm{\Delta}S$ both are $+ ve$ for spontaneous change and $\mathrm{\Delta}H = + ve$ for endothermic reaction
