2.3: First-Order Reactions - Chemistry LibreTexts
2023年2月13日 · The differential equation describing first-order kinetics is given below: \[ Rate = - \dfrac{d[A]}{dt} = k[A]^1 = k[A] \label{1} \] The "rate" is the reaction rate (in units of molar/time) and \(k\) is the reaction rate coefficient (in units of 1/time).
First-Order Reactions (Chemical Kinetics) - Free Study Material
The integrated rate equation for a first-order reaction is: [A] = [A] 0 e-kt. Where, [A] is the current concentration of the first-order reactant [A] 0 is the initial concentration of the first-order reactant; t is the time elapsed since the reaction began; k is the rate constant of the first-order reaction
