Question

fill in the missing words
for the reaction $hgs(s)+o_2(g)
ightleftharpoons hg(l)+so_2(g) delta g < 0$. the negative value of $delta g$ means that the reaction is

in the forward direction. in the reverse direction the reaction is

.

Explanation:

The Gibbs - free energy change ($\Delta G$) determines the spontaneity of a reaction. A negative $\Delta G$ indicates that the forward reaction is spontaneous, meaning it proceeds without the need for external energy input under the given conditions. A positive $\Delta G$ for the reverse reaction means it is non - spontaneous and will not occur without external intervention.

Answer:

spontaneous; non - spontaneous
