Condition suitable for forming atomic chlorine from molecular chlorine is — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The reaction is Cl₂(g) ⇌ 2Cl(g). Bond breaking is endothermic, so the forward reaction is favored by high temperature. Since the forward reaction increases the number of gaseous moles (from 1 to 2), it is favored by low pressure according to Le Chatelier's principle. Therefore, correct answer is B,C.
