WebA first-order reaction is a reaction where the rate is dependent on the concentration of only one reactant. Because of this, it is also called an unimolecular reaction. The units of the rate constant for a first-order reaction is 1/s. The first derived form of the rate equation is: l n [ A] = − k t + l n [ A] 0. WebFeb 14, 2024 · The number of reacting species (atoms, ions or molecules) taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction is called the molecularity of a reaction. Generally for a reaction aA + bB → cC + dD. Molecularity = a + b.
