(d) : Cl2(g) + 3F2(g) ⇋ 2ClF3(g) ; ΔH = –329kJ.
Favourable conditions:
(i) As the reaction is exothermic, hence decrease in temperature will favour the forward reaction.
(ii) Addition of reactants or removal of product will farour the forward reaction.
(iii) Here Δn = 2 – 4 = –2 (i.e., –ve) hence decrease in volume or increase in pressure will favour the forward reaction.
