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 … WebA theoretical equation that describes the velocity of a process is called a rate law. As we stand on the outside and study the reaction of A P, we can only measure the velocity of the reaction, but are unable to measure the rate constant. This is, however, easily done by rearranging the equation and integrating: d[A]/[A] = -k dt or

WebFeb 21, 2024 · For first order, the units are 1/s or s^-1. For second order, the units are 1/M*s or L*mol^-1*s^-1. You will notice that there is a pattern here. Every time the order is increase by one we divide by M or mols/L. So therefore, for a third order, the units of k would be 1/M^2*s or L^2*mol^-2*s^-1. Hope this helps!
