First-order reactions
WebFor a first-order reaction, the half-life is given by: t1/2 = 0.693/k For a second-order reaction, the formula for the half-life of the reaction is: 1/k [R]0 Where, t 1/2 is the half-life of the reaction (unit: seconds) [R 0] is the initial reactant concentration (unit: mol.L -1 or M) WebOct 27, 2024 · The key difference between first order and pseudo first order reaction is that first order reactions proceed at a rate that depends linearly only on one reactant concentration whereas pseudo first order reactions are second order reactions that are made to behave as first order reactions.. The term “pseudo” means “not genuine”. …
