http://pharmaquest.weebly.com/uploads/9/9/4/2/9942916/order_of_reaction.pdf WebYes, zero-order reactions have a half-life equation as well. We 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. WebWe can, but only for a first order reaction. Each order has its own half-life equation. Zeroth order: ([A0]/2k) First order: (ln(2)/k) Second order: (1/k[A0]) So the zeroth and second order require us to know the rate constant and the initial concentration, while the first order only requires the rate constant. Hope that helps. how do market forces affect organisations
