First order second order zero order graphs
WebUnlike with first-order reactions, the rate constant of a second-order reaction cannot be calculated directly from the half-life unless the initial concentration is known. Zero-Order … Webmore. This is grade-12/college-level but if you're curious I will show you below. So for a first order reaction -- we have the reaction equals the rate constant times the concentration of the (only) reactant --> R = k [A] 1. Then we choose to re-write R as -Δ [A]/Δt. and we get -Δ [A]/Δt = k [A] 2. Then we bring -Δt to the right side.

Comparing Eq (ii) with the equation of a straight line i.e y = mx+c and thereby on plotting Eq(ii), we get a graph where slope = k/2.303. For first-order reactions, the ... WebMar 8, 2024 · Therefore, a zero order reaction is usually graphed as [A] vs. time, which should be a straight line. If it isn't a straight line then it is not a zero order reaction. For first order reactions, the integrated rate law is ln [A] = -kt + ln [A]initial. In this case, a graph of ln [A] vs. time should create a straight line. Top. Silvino Jimenez 1A.
