Benzene can be sulfonated by concentrated sulphuric acid: C6H6+ H₂SO4 C6H3SO3 + H₂O* This reaction occurs by the following three-step mechanism: Step 1: H₂SO4- SO3 + H₂O Step 2: SO3 + C6H6 Step 3: C6H6SO3 + H₂O C6H3SO3 + H₂O* Determine the relationship between the equilibrium constant for the net reaction and the elementary steps. Order terms in the numerator and denominator by mass or step number and separated products and reactants with a single "/". Enter subscripts as ordinary letters or numbers followed by superscripts in parentheses. Do not include Keqin your answer, or an indication that the value is at equilibrium, e.g. enter Ken (PH20) eq as "pH2O(2)" and k₁/k1 as "k1/k-1".
