WebA 1 st order rate law shows that the rate is dependent on the concentration of one reactant, though other reactants may be present. A 2 nd order rate law indicates that the rate is dependent on the concentration of two reactants in the reaction. Those reactants can be the same, i.e. rate = k [A] 2, or different, rate = k [A] [B]. WebJan 30, 2024 · more. 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.
