(A) The equilibrium constant $K$ decreases from $2$ to $1 \times 10^{-3}$ as the temperature increases from $273 \ K$ to $298 \ K$. According to Le Chatelier's principle,for an exothermic reaction,the equilibrium constant decreases with an increase in temperature. Since the value of $K$ decreases as the temperature increases,the forward reaction (formation of $C$ and $D$) is exothermic.

exothermic
B
endothermic
C
can't be determined
D
there is no relationship between $\Delta H$ and $K$
