In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant). sebaceous cyst on the backWebAug 12, 2024 · The order of a chemical reaction is the sum of the values x and y.A second order reaction is a reaction where x + y = 2. This can happen if one reactant is consumed at a rate proportional to the square of the reactant's concentration (rate = k[A] 2) or both reactants are consumed linearly over time (rate = k[A][B]).The units of the rate constant, … pulseira smart band 7
