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. WebIn some of our examples, the reaction orders in the rate law happen to be the same as the coefficients in the chemical equation for the reaction. This is merely a coincidence and …
WebJan 2, 2024 · For a general chemical reaction: aA + bB → cC + dD the rate of the chemical reaction may be calculated as: Rate = k [A] a [B] b Rearranging the terms, the rate constant is: rate constant (k) = Rate / ( [A]a[B]a) Here, k is the rate constant and [A] and [B] are the molar concentrations of the reactants A and B.
