How to Calculate Half-life of a Second-order Reaction

WebDec 11, 2024 · Your equation gives d x d t = k [ A] 0 [ B] 0. This is exactly what's expected, as this is the maximum value of the rate of product formation. Let's arbitrarily assume that [ A] ≥ [ B]. Then the reaction is done when x = [ A] 0. If you plug this value into your equation, you find that d x d t = 0 which is also correct. WebFor a second-order reaction, t1/2 = (1/k[A]0) . 7. How is the order of a reaction generally determined? The reaction order cannot be determined by the stoichiometry of the reaction. It can only be determined by running controlled experiments where the concentrations of the reactants are varied and the reaction rates are measured and analyzed.
