Half-Life of First, Second and Third Order Reactions for JEE

WebJun 20, 2024 · In first order reaction, half life is a time in which half of reactants are converted into products. If a is initial concentration, then after the first half life the amount of reactant decay is 1/2a. After second half-life amount of reactant decay is (1/2a) (1/2a)=1/4a. After third half life amount of reactant decay is (1/2a) (1/2a) (1/2a)=1/8a. WebJun 30, 2015 · Half-life (t½) is the time required to change the amount of a drug in the body by one-half during elimination. The two main factors which affect drug half-life are volume of distribution and clearance; the formula for half-life is (t½ = 0.693 × Vd /CL). The 0.693 factor is in fact the logarithm of 2, which represents the fact that drug clearance typically … WebWe can derive it the same way we derive the half-life equations for the first and second-order reactions. The given integrated rate law of a zero-order reaction is: [A]t = -kt +[A]0. At half-life the concentration is half of its original amount, so [A]t = [A]0/2. greenmeadows centre stoke
