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 (products/reactants AT EQUILIBRIUM) to see if the reaction is at equilibrium or not. If Q=K, the reaction is at equilibrium. Comment WebIf a reaction proceeds nearly to completion, then the concentrations of the products is much larger than the concentration of the reactants and the value of the equilibrium constant is very large (much greater than 1). If the reaction only makes a small quantity of the products at equilibrium, then the value of the equilibrium constant is very ...

WebOct 10, 2024 · The reaction quotient (Q) describes the state of a system with respect to equilibrium, and tells you if a chemical reaction will proceed, and if so, in what direction. Mathematically, it is the equlibrium constant expression, but using the concentrations of any system, whether it is at equilibrium, or not. For a chemical reaction to occur, Q ≠ K. WebJan 30, 2024 · Calculating K p. Referring to equation: \[aA + bB \rightleftharpoons cC + dD\] \[K_p = \dfrac{(P_C)^c(P_D)^d}{(P_A)^a(P_B)^b}\] Partial Pressures: In a mixture of gases, it is the pressure an individual gas exerts.
