WebApr 22, 2024 · Part 2: Reaction equilibria a) Equilibrium constant and reaction quotient . Certain chemical reactions known as reversible reactions can progress either forwards or backward.In other words, these reactions are able to progress “forwards,” creating products from the reactants, and also progress “backwards,” creating reactants from the products. WebFeb 21, 2024 · For a zero order, the units of k are M/s, or mol*L^-1*s^-1. 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. small pianos for small spaces https://bowlerarcsteelworx.com
