In a zero order reaction 20
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.
