Reactant concentration chang
WebSince the reactant concentration decreases as the reaction proceeds, Δ [H 2 O 2] is a negative quantity. Reaction rates are, by convention, positive quantities, and so this negative change in concentration is multiplied by −1. The table below provides an example of data collected during the decomposition of H 2 O 2. WebMay 1, 2024 · When the concentration of a species Is changed according to Le Chatelier's principle the equilibrium system will change it's rates of the forward and backward reactions so as to balance the concentrations thus keeping the equillibrium constant the same.
