In a first order reaction the concentration
Did you know?
WebTo determine [Ao], the initial concentration of a reactant, we need to know: The final concentration, [A]. The length of time, t, the reaction ran to reach the final concentration. The order of the reaction or enough information to determine it. The rate constant, k, for the reaction or enough information to determine it. WebAug 8, 2024 · The rate of a first-order reaction is proportional to the concentration of one reactant. A common example of a first-order reaction is radioactive decay, the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments. The rate law is: rate = k [A] (or B instead of A), with k having the units of sec -1
WebWhat is a First-order Reaction. A first-order reaction is a chemical reaction where the reaction rate depends linearly on the reactant’s concentration. In other words, if the … WebThe analysis for this is more complicated than for first order reactions but we can simplify by using pseudo first order conditions. If we run the reaction above with 1 mmol of A and 100 mmols of B in 10 mL of solution at the start of the reaction, the concentration of A will go from 0.1 M to 0 M while the concentration of B will go from 10 M ...
