WebThe reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products. The Q value can be compared to the Equilibrium Constant, K , to determine the direction of the reaction that is taking place.

WebMay 31, 2016 · As the reaction progresses towards equilibrium, the concentrations of A and B will decrease as more C is formed. If we keep measuring the concentrations of A, B and C, and calculating [C]/ [A] [B] (which we are calling Qc) then we will find that Qc gets closer … WebQ = K Reaction is already at equilibrium. Also, if any reactant or product is missing in the initial mixture, the reaction will shift in the direction forming some of that component. So, let’s see how the reaction quotient is used to determine the equilibrium concentrations.

WebQ is used to determine whether or not the reaction is at an equilibrium. At any given point, the reaction may or may not be at equilibrium. By calculating Q (products/reactants), you can compare it to the K value … WebOct 10, 2024 · In this section we will mathematically describe the concentrations of products and reactants for an system that has arrived equilibrium in terms of an Equilibrium constant.

WebJan 26, 2024 · The reaction may be said to be "complete" or "quantitative." If the value for the equilibrium constant is small, then the equilibrium favors the reaction to the left, and there are more reactants than products. If the value of K c approaches zero, the reaction may be considered not to occur.
