Which of the following equilibrium is not affected by pressure?

Explain the effect of concentration on equilibrium when two drops of $0.2 \ M$ potassium thiocyanate $(KSCN)$ are added to $1 \ mL$ of $0.2 \ M$ iron $(III)$ nitrate solution.

When pressure is applied to the system $Ice \rightleftharpoons Water$,what will happen?

Does the number of moles of reaction products increase,decrease,or remain the same when each of the following equilibria is subjected to a decrease in pressure by increasing the volume?
$(a)$ $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$
$(b)$ $CaO_{(s)} + CO_{2(g)} \rightleftharpoons CaCO_{3(s)}$
$(c)$ $3Fe_{(s)} + 4H_{2}O_{(g)} \rightleftharpoons Fe_{3}O_{4(s)} + 4H_{2(g)}$

According to Le $Chatelier$ principle,if heat is given to a solid-liquid system,then:

Under which conditions of temperature and pressure is the dissociation of molecular hydrogen into atomic hydrogen favored?
