1.	Does the number of moles of reaction products increase, decrease or remain same when each of the following equilibria is subjected to a decrease in pressure by increasing the volume? (a)PCl_(5(g)) hArr PCl_(3(g)) +Cl_(2(g)) (b)CaO_((s)) + CO_(2(g)) hArr CaCO_(3(s)) (c)3Fe_((s)) + 4H_2O_((g)) hArr Fe_3O_(4(s)) + 4H_(2(g))
Answer» Solution :(a)`PCl_(5(G))hArr PCl_(3(g)) +Cl_(2(g))` increase (b)`CaO_((s)) + CO_(2(g)) hArrCaCO_(3(s))` decrease (c) `3Fe_((s)) + 4H_2O_((g)) hArr Fe_3O_(4(s)) + 4H_(2(g))` no change . Because, the pressure is decreases so, the REACTION occurs towards the less mol of gas PHASE to high mol means reaction TAKE place in such way moles of gases phase increases.
