Web3 concentration of N 2, H 2, or NH 3.Say we monitor N 2, and obtain a rate of - d[N 2] dt = x mol dm-3 s-1. Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d[H 2] dt = 3x mol dm-3 s-1.Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s … Web25 aug. 2024 · 14.8: Theoretical Models for Chemical Kinetics Learning Objectives To use graphs to analyze the kinetics of a reaction.

However, the units of \(k\) vary for non-first-order reactions.

WebThe order (reaction order, kinetic order) of a reactant or other participant in a reaction is defined as the exponent of the concentration of that species in the rate equation, written as a power law. The overall order is defined as the sum of the exponents of all concentrations in the rate equation.
