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. ( 1 vote) Data WebNov 5, 2024 · A first order reaction takes 100 minutes for completion of 60% of the reaction. Find the time when 90% of the reaction will be completed. ...

WebThis means that the initial reaction rate is not dependent on [A], so the reaction is zero order with respect to A. (May also justify using mathematics as shown in part (b).) One point is earned for the correct order and for the justification. (b) Determine the order of the reaction with respect to reactant B. Justify your answer. 2 1 WebCOMPARISON OF FIRST, SECOND & ZERO ORDER REACTION A tablet decomposes after one year to 75% of its initial concentration. In the following table the ...
