WebHalf-life Formula for Second-order Reactions. There is a special form of the integrated rate equation we can use called the half-life equation. A reactant's half-life is the time it takes … 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.
